Azio BTD-V400 - CSR Harmony (Bluetooth Apt-X) Software and Drivers Details

32 and 64 bit drivers.

CSR Harmony is Bluetooth + Apt-X software for computers. Currently there is not enough information about the software, so I'll try to uncover some details. The software comes with the Azio USB Micro BT 4.0 Adapter BTD-V400.

Links:


The splash screen when install begins.

There are a lot of configurations available; you can change these later on.

Method of pairing devices: just go to the blue Bluetooth icon on the notification area and right click.

If your audio device (speaker, earphones, other) is in pairing mode it will show up here.

First time pairing will show like so.

When the computer connects to an Apt-X device it will show this.  This is one way of determining whether a device has Apt-X or not.  There are other methods to find out whether your device has Apt-X, for example if you have developer tools on Apple Mac you can try to find the codec being used--it's likely to be marked as unknown "Sent Command - SetConfiguration - ACP SEID [5 - Audio Sink] - INT SEID [2 - unknown unknown] - Audio non-A2DP" (courtesy of Jerome O'F.)

To enable the audio device: Press the Win key and type "Manage Audio Devices" and open it.

Windows will show two Playback devices, select the second one for high audio quality, make sure to press the "Set Default" button.  The first option will enable the microphone, but the audio quality for music is crappy.

If you add several Bluetooth audio devices it would be good to rename the device.  Just type in the desired name and click Apply button.

By default audio quality is set to 16 bit 44100 Hz (CD Quality), but you can change this to 16 bit 48000 Hz (DVD Quality).  The higher audio quality can be problematic though (packets are delivered wirelessly, but it may cause a delay or "pops").  I would recommend having it on the CD Quality.

The About CSR Harmony Wireless Software Stack screen; this shows version 2.1.63.0

If you want to view all of your Bluetooth devices you can press the Win key and type "Bluetooth devices".

The Braven 650 speaker options.  If you double click on A2DP it will activate high quality audio (just like on the "Manage Audio Devices" screen.  Handsfree Profile allows mic but lowers the audio quality.  The Braven 650 does allow play/pause.

JayBird BlueBuds X has the same options.  The BlueBuds X has play/pause/next/previous buttons.

Monster Clarity HD lacks the AVRCP Target option (which I'm unsure what it means).  The ClarityHD has play/pause/next/previous buttons.

The Soundmatters foxLv2 Platinum has the A2DP (Sink) high quality audio and Handsfree Profile.  Although the foxLv2 Platinum is the most expensive portable speaker the device does NOT have play/pause/previous/next buttons.

  3. Hello, I have a big problem. Everytime I plug my csr powered bluetooth 4.0 device into my computer, the Harmony software says "You don't have a valid license to start CSR Harmony."
    I can't find anything about this problem. Maybe you can help me. I am running Win7.

    1. Reinstall drivers, ensure you do so with Admin rights (right click on program and "Run as administrator." First, try to install the drivers from the disc, if that does not work then download and attempt the online drivers.

    2. I got the same problem. I tried CSR Harmony 2.1.63.0 on 2 different PCs - one with Win7 32bit, the other one with Win7 x64.

      And I always get the same message: "You don't have a valid license to start CSR Harmony."

      I also tried it with the Toshiba Bluetooth Stack - it works, but it doesn't have any Aptx support and is only a trial version (30 days).

      Any ideas?

    3. I copied the software from the disc onto a thumbdrive, and then installed from that thumbdrive onto my X230T. The web and disc software might behave differently though.

  4. Thanks for your review. I wonder if Azio BTD-V400 can receive aptx stream from other aptx-enabled device? Does Harmony software allow this?

    ReplyDelete

    1. That is a very good question and at the moment I'm unsure. I know that usually when Bluetooth dongles work as a "receiver" they change their audio profile, which enables them to receive audio through a device's mic, but this also drastically lowers the audio quality on the transmitter side (ie what you are hearing during a phone/skype conversation). From the software side I noticed the Windows profiles to be identical in both normal BT and Azio's Apt-X BT. As for the proprietary software... well I have not fully explored it.

  5. Hi Jesse, I tried to install the CSR Harmony on two different pcs (both run win7 enterprise 64bit), both reported error during installation(runtime error!), although the software can still finish installation. I can added device, and the csr harmony can pair the bt device (I tried Avantree Saturn and a customer bluetooth device), but when it try to install the drive for the paired device, it failed. Which os did you used in your setting? I saw people complained the same problem in win7 64bit os in amazon and newegg customer review. Any suggestion or tip are appreciated. Thanks, -Yuan

    1. I have used Win 7 Pro 64-bit. Try this:
      1. Open My Computer, right click on the disc drive and select "Open in new Window"
      2. Open the x32 or x64 folder, depending on your Win 7 version.
      3. Right click on the installer and run the software as an Administrator.

      Hopefully that works.

      Delete
    2. Thanks for the suggestions. Unfortunately this doesn't work.
      After installed the software (despite the error message, it still finished the installation and claimed successfully installed), the windows even log reported similar error message for different csr bt exe file, "Activation context generation failed for "C:\Program Files\CSR\CSR Harmony Wireless Software Stack\BtSwitcherService.exe". Dependent Assembly Microsoft.VC90.ATL,processorArchitecture="amd64",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8" could not be found. Please use sxstrace.exe for detailed diagnosis."
      I will try to find a pc with win7 pro 64bit and see if it will work. I guess I should try to contact azio to see if they have any solution. Anyway, thank you for your time. -Yuan

    3. Might want to Google "Microsoft VC90 redistributable package" in case you are missing certain files. It could be the VC++ 2008 SP1 version... but dunno.

      Delete
    4. The problem is not really a vc++2008 redistributable package, although it looks like. I tried to install both vc++ 2008 redistributable package with or without sp1, no luck. I tried install the software in win7 professional 32 bit, everything works fine. I can pair the dongle with Avantree Saturn and shown apt-x logo after connected. Sound quality is great. Still can't figure out why it doesn't work on 64bit win7 enterprise. Maybe I should try to find one win7 professional 64bit machine and try it.
      Thanks for your time. I already contact the amazon and may just return it to save trouble.

  12. Is there any way to get the connection to establish automatically after the BT radio is turned on? I currently have to go through several steps to establish the BT connection every time I turn off the radio.

    ReplyDelete
    Replies
    1. Usually the problem is on part of the receiver (ie. speaker, headphones). The receiver needs to be seeking, and the Azio (transmitter) simply has to respond. If your receiver does not seek automatically then you have to manually do it, this can be a chore.

      Now, you can affect the Azio's function. This would depend on software--which sometimes crashes, or if someone manually turns off "all the radio features of a laptop/tablet" and the software fails to acknowledge when the radios are turned on again. It's best for the Azio if the user does not turn off radios.


      Which speaker or headphones do you have?

  13. I bought a Logilink BT0015, which have exactly the same Bluetooth stack on CD as linked in the post.

    Three things:

    1. On Windows 8.1, when trying to make a RDP session from the computer that have installed the Stack, the RDP client crashes. Solution: Remove or Rename the file c:\Program Files\CSR\CSR Harmony Wireless Software Stack\BLEtokenCredentialProvider.dll. Looks like the Stack is able to use some bluetooth device for credentials, but that does not work with the rdp client on Windows 8.1.

    2. Same issue with Office 2013, the PIM addin let Outlook crash. But the addin gets disabled after the second crash.

    3. With another adapter on Windows 8.1 with its own Bluettooth Stack my Creative 350 was detected as Headset and the HSP was used. Which gave a good audio input (1 channel 16 bit 48khz). Now with CSR I only get HFP (1 channel 16 bit 8khz).

  14. I installed the CSR driver on Win8.1 on a Microsoft Surface Pro 2 and there was no error during Installation (nevertheless I did not have to accept any particular "Driver Installation" alert during Installation...) and the CSR Bluetooth stack appeared in the list of installed Software. However, when connecting my Harman & Kardon Apt-X headset, not the Cambridge driver was active, but a Microsoft A2DP driver dated August 2013. This MS driver shows a dedicated speaker device for the Harman (besides, there was a headset incl. microphone device as well) and reports 2 channels, 44.1kHz CD Quality audio. There is no trace of the CSR driver around. I cannot even deactivate the driver or load a new driver manually, These fields are greyed out.

    Also, CSR seems to have installed a strange Outlook plug-in which makes my Outlook crash upon start-up.

    After spending a week or so investigating if the Azio Apt-X usb adapter will work or not with windows 8.1 64bit I still haven't found an answer. Basically I understand that it will work but not using Apt-X codec. Apt-X is the only feature I care about since I'm using it for my Beats Studio Wireless Headphones. I would get a more expensive adapters but even the ones I looked are experiencing similar issues, that and the fact I need at least 4 of them.

    Can someone please give me a clear answer here, will this adapter and Apt-X codec work with Windows 8.1 x64?

    If not, does anyone have another adapter (with Apt-x) that works with this setup?

    Thanks.

    1. This isn't going to answer your specific question, but for what its worth I had no problems installing on Windows Surface Pro 1 with Win 8.1 (almost certain Surface Pro is 64 bit).
      So, yes, you will have no problems getting audio output via the adapter. (make sure your .net is up to date as per Azio support site)
      But ... sorry, can't confirm that Apt-x will be selected because I still haven't made a decision on what Apt-x receiver to purchase yet.
      From what I can see, Bluetooth is fully offloaded to CSR Harmony stack, so 98% sure that once I get a Apt-x enabled receiver it will just work

    1. I am using apt-x with Windows 7 64bit and it works fine for me!
      My devices: Logilink BT0015 with CSR Harmony stack from its CD and AKG K845BT as headphones. On connection the CSR aptx screen confirms the use of aptx and as profiles I have 44kHz CD Qualit├Ąt or 48kHz DVD Quality to chose from.
      (Remark: The Outlook plugin crashes on my PC, too. But I only use the audio transmission, so that is no problem for me.)

  17. Hello! I bought the new ASUS EB50N headset (Bluetooth 4.0) and bought a Bluetooth-USB-Adapter Mini-Bluetooth P008-USB06H by www.atlantis-land.com (Bluetooth ver. 4.0) for the PC, which disc contained the software CSR Harmony. I installed everything (using Win 7) as described and it works well for watching TV, playing but just for Skype i have some problems:
    I allowed in skype the CSR-plugin and skype recongnizes my headset, but the soundquality, as my partner with who i am talking says, is very bad and it happens continuously that the quality of sound get worse and worse, till i cant hear anything anymore (like with the mobilephone if you have a bad connection).
    What can i do?? I tryed to find in the internet some hints and support, but cant find anything.
    Can you help me?
    Thanks!

  18. Great write-up thanks.
    I'm running 8.1 on a MS Surface Pro 1 and using the Azio BTD-V400 only to get apt-x. All I had to do was disable internal Surface blue tooth and all instructions in the post above were relevant and useful.
    I have read elsewhere that correct .net version is key, so if you're having issues on Win 8.x check your system is fully up to date

    1. Press and hold the button on the BM10 until it flashes purple, whilst searching for Bluetooth devices on the PC. The BM10 will show up.

      The problem I am having is that whilst it is paired with it, I cannot get it to stream to the BM10. The A2DP Sink on the BM10 is showing as disconnected and not responding.

      Also I have nothing showing on audio devices other than my realtek speakers. There is no Bluetooth audio there at all.

      On other Bluetooth USB adaptors with Apt-x, (Eg the Sennheiser BT500) the Bluetooth audio device shows up as a selectable audio device, although I couldn't get the Bluetooth to work on that, hence why I got the V400.

      Oh the irony.

      So how can I get my laptop to recognize the audio Bluetooth, sink A2DP and stream music to the BM10?

  21. From many of the questions asked it seems clear that a lot of people still don't get the basic equation which is simply that both the transmitting device and the receiver device both have to have the aptx codec. A quick visit to www.aptx.com will get you a pretty complete list of every device.

    Personally, I would try to purchase a device with the drivers embedded. Plug and play instead of having to install from a cd or dvd. Furthermore, what was described in the initial installation was relatively straightforward. Plug in the adapter and install the drivers for the transmiter. He then connected to a Soundmatters foxl which is a aptx enabled speaker, iirc. How this got to it being simply a matter of trying to install drivers for a specific piece of hardware to the notion that these drivers are unversal is pretty impressive stretch. When he installed the drivers from that transmitter, he sure as heck installed a lot more than one codec. I imagine the entire bluetooth stack was installed and it wasn't universal ianas nature.

    A quick visit to any of the android forums will divulge why I think this isnt going to work. There has been many attempts by some pretty good modders to get the aptx codec running on rooted phones. AFAIK, no one has been successful.

    Aptx is proprietary and they charge for their codec. They were/are first and foremost a company geared to large commercial broadcasters. They aren't some new kid on the block, they're just relatively new to the individual retail market. When you're entire income revolves around licensing fees, it's safe to say they aren't going to let a licensee throw out a dvd that contains, in essence, an enterprise edition of the codec IMHO. I think that's why we're seeing all the problems arise.

  22. I have the BTD-v400 installed on a Windows 8.1 32-bit system. I used it for A2DP non-apt-X for months and it has been outstanding. When I finally got an apt-X receiving device, a speaker, a few weeks ago it paired right up with the apt-X codec. I also use Bluetooth keyboard and mouse connected through the BTD-v400. Most of the problems I read about are with the Windows 7 64-bit system.

    1. I find that hard to believe, but believe you Jim. I tried a Sennheiser 1 USB Bluetooth BTD500 and the Azio,both are supposed to support Apt-x Codec and A2DP. However both will not stream to my Sony BM10 receiver, which incidentally, also supports Apt-x codec. The Bluetooth driver of the Sennheiser would not work in Windows 8, where as the Azio Audio drivers won't work. I give up on it all. It's all junk. If you are lucky, it will work, for most it won't on a new PC.

    2. I am getting to thinking that Apt-x codec just doesn't work with 64 bit OS to be honest, as most things don't.

      Delete
    3. Both the Sony BM10 Receiver and the Azio BTD-v400 support Apt-x codec and A2DP. The Azio recognizes it to pair them, but cannot stream anything. The problem I have is that the Bluetooth Audio Renderer, listed in Audio Devices, that loads with the Azio and stack is showing as 'Not Connected' and cannot be selected as an audio device. Thus I cannot stream anything.

  28. Hi everybody,

    I can't manage to connect (after succesful pairing) the Sony BM10 with the Azio BTD-V401. Neither by waiting for the BM10 to initiate the connection, nor by forcing it by clicking on the A2DP service icon on my PC. Strangely, sometimes, by unplugging and replugging the Sony it actually connects and everything looks like Jesse has described above. Unfortunately this is not consitent every time and, as soon as another device pairs with the Sony, the previous connection is lost. Has any of you solved this problem? Or, can anybody suggest what to change: dongle or audion receiver?

    3. Hello everyone,

      I have a wonderful news : I SUCCEEDED in connecting the BM10 with a CSR 4.0 bluetouth dongle (mine is BT0015) !

      Here is the sequence of operation to follow :

      1. Install the CSR Harmony Wireless Software Stack
      2. Plug the BT0015 dongle in a free USB port
      3. Open the Bluetooth Setting Window and verify all check boxes are checked - Apply
      4. Add Device - All
      5. While the computer searches for new Bluetooth devices, push and maintain the pairing button on the BM10
      6. When the BM10 device is discovered, double clic on it to start the pairing process
      7. On the My Bluetooth Devices double clic on the icon BM10
      8. Right clic on the A2DP icon and clic on Connect
      9. Now carefully look at the led on the BM10 - it should be white
      10. After one or two seconds, the white led will flash blue once
      11. Count 1 and 2, and immediately push once the pairing button on the BM10
      12. The white led will flash in blue some times and then will become brilliant blue
      13. The connection is now successful and you will see on your computer screen the APTX logo meaning that the devices are communicating in APTX.

      I believe there is a problem in the sequence of codes sent to the BM10 by the Bluetooth dongle on the computer. When connection starts, the BM10 led flashes once and then becomes again white, as if it was still waiting for an additional code that doesn't come. By pushing the pairing button at the right time, the connection can be established. The most important thing is to exactly count 1 and 2 after the led firstly flashed and then push the pairing button on the BM10 (step 11). Don't miss this small time frame, because in such case you will receive the message "Device doesn't respond" and you will need to restart the process.

      Enjoy the nice APTX sound !!!

      Thanks for sharing!
      I tried you method and it works, unfortunately you need all the manual operations everytime you diconnect and reconnect.The solution is unfortunately not helpful for me because in my case several devices alternate as a music source (laptop, iphone, desktop) and actually one of the feature of the BM10 is the possibility to store 8 different profiles.

      Thanks

    6. Fabrizio,

      I agree, the solution above doesn't suit me neither. But we have at least the explanation : this CSR Harmony driver is not compatible with the BM10. I will look on the internet to find another Bluetooth V4 dongle with APTX and class 1 that does not use this driver. This may eventually work. I will tell you witch one I found. Of course, I would appreciate if you could share the initiatives taken on your side.

    8. I just ordered the BTD 500 (http://en-us.sennheiser.com/btd-500-usb). It's a class 2, APTX, Bluetooth 3.0. I read comments saying it works with the BM10.

      Of course I would have prefered a class 1, but the I am afraid, in such case I need to choose another receiver. Have a look at this page (http://www.aptx.com/category/receivers-transmitters) for all APTX receivers. The Brightplay HD Receiver is a 4.0 that looks better than the BM10.

  30. Thanks for this, this is the only software which works with the cheap CSR 4.0 dongle I bought from Ebay. The only thing is, it doesn't reconnect automatically to the A2DP receiver, I have to reconnect manually all the time.

  31. I am trying to auto select (using an AutoHotkey script) the default Audio Playback device for Windows XP as one of several Bluetooth connected devices. I am using a Logilink BT0015 USB Bluetooth dongle with the CSR Harmony Bluetooth stack software. I can determine the friendly name of a connected Bluetooth device from the registry but I have failed to find a link between it (or its Bluetooth address) and the name of the Bluetooth device as it appears in XP's "Sounds and Audio Devices Properties" window (Audio tab). For instance my "BT Speaker" can appear as "Bluetooth Stereo Audio" or "Bluetooth Stereo Audio (x)" where x is a number from 2 to 6. Does anyone out there know how to link these two parameters ? At the moment the best I can do is cycle through the listed Bluetooth devices and send a chime to test if the "Bluetooth Stereo Audio (x)" refers to the currently connected device. Any help would be appreciated. Thanks !

  33. CSR Harmony is an END OF LIFE product and the (extremely unfriendly, cold and unprofessional) CSR Support does not give ANY support for it.
    The problem is, you WILL need support, because it is a crappy buggy software.
    In my case for example I got it with the Azio BTD V401 (another Brand which I HIGHLY suggest to AVOID for having an horrible support).
    I first installed only the Dongle and all worked fine, my mouse, Logitech M555b was recognized, was even listed among the System Devices, and the Logitech SetPoint software recognized it well and showed the Mouse Tab with the options to configure its special functions.
    I then installed the CSR Harmony.
    Immediately the mouse disappeared from the System Devices and the Mouse Tab from SetPoint.
    I have now Aptx, but I have lost ALL special functions of my mouse, which works now as a normal (and very expensive) 2 Button mouse.
    CSR refuse to give ANY support and says I must ask Azio, Azio does not even answer to my emails.

    So I had to buy the Sennheiser BTD 500 and use that for music and keep the Azio (without CSR Harmony) for the Mouse.
    The Sennheiser has got slightly better Sound Quality but lesser Range.
    SO now with my Headphones I have a blind spot in my house.
    And I am thinking to just change mouse and use again the Azio with CSR Harmony.

    But if you do not need more than 10 mt Range, I HIGHLY suggest you the Sennheiser.
    CSR and Azio are crap.

    1. Sorry for your troubles but the Azio BTD V401 worked for me on my 2013 Dell i5 desktop (BestBuy Black Friday 2013 doorbuster), pairing it with my Bluetooth headphones MEElectronics Air-Fi Matrix2 (with aptX) & Arctic P253BT (w/o aptX). Btw, my keyboard & mouse are not Bluetooth capable. I installed it this way: downloaded the driver (about 500mb in size!) from their website, installed it then immediately restarted the computer. Only then did I insert the dongle. I did NOT follow the instruction to "insert the dongle first, then install CSR" crap :) After installing, you have to set the Bluetooth Audio Renderer the default Playback device and set the sound to DVD quality, as described by JBA above. Now, everytime your aptX Bluetooth headphone connects, the CSR aptX logo will appear to let you know that an aptX connection has been made. All's been going well for now except for this: I noticed that while listening to a song on my hard disk with foobar2000 using my aptX Bluetooth headphone, and I open a new tab in Google Chrome, the song would stop and after a few seconds, will start again from the beginning! Am still trying to fix this :(

      Hope this helps... Cheers! :)

    2. Hi, I thank you for the answer.
      I am pretty sure I did already try with this combination of installing the Stack before plugging the Adapter.
      I did all possible tests. There is no solution.
      But I think you miss the point. It makes no much sense that you tell me "it worked for me" if you do not even have a BT mouse. Because my problem are with the mouse, not with the headphones. Besides, I am not sure I would say that it worked for you, given the problems you are having :)

      For my case it would only be really helpful if somebody who has got a logitech BT Mouse, or some other BT mouse which have special features, configurable buttons, and a special software for that, would tell me if he had problems with the CSR Harmony or not.
      But if you only tested it with your Headphones, well, I also had no problems with my Headphones :)
      As said, the quality of sound is pretty good.
      When I use my mouse, than I have problems. First, things slow down. Apparently the hardware in the Azio is not so good and can't handle two profiles together (HID and A2DP) very well.
      Then, the CSR Harmony disables my Mouse from the system and closes it in its own Stack, far from SetPoint.

      These are the problems.
      When I say that CSR and Azio are crap what I mean is not that nobody ever can find this product useful.
      Surely if you only connect a Headphone you will find it probably useful, although in that case I would still prefer Sennheiser (better sound, and no problems. Only difference, Sennheiser 30ft, Azio 35 to 40ft range).

      But CSR is discontinuing the ONLY Stack available for Aptx! This is NOT nice.
      And its Support is very unfriendly.
      Azio sells sub-par hardware, with a discontinued software, answering no email when people ask about that, and giving false info about the specs (this thing has NOT 80ft, NEVER).

      This IS crap :)

      Cheers!

  34. Hi Mr. Jesse,
    I have some problems with this software (sorry for my bad English).
    First of all, thanks that you shared this software cause my notebook doesn't have a CD driver to install CSR harmony.
    This Software worked well for me with my beats audio wireless and logilink adapter, really thanks.
    But now i dont need it anymore and i have uninstalled it from control panel like other normal softwares.
    However here is what i received when trying to do that:
    "There is a problem with this Windows Installer package. A script required for this install to complete can not be run. Contact your support personnel or package vendor. Custom action KillOfficeApplicationMsg script error - 2147023838, : line 7, column 1, "
    I am not sure but before uninstalling it i have carelessly deleted a file with name "uninstaller" somewhere on driver C (maybe that is the cause)
    Now in control panel Csr is still there and every time i try to uninstall it i get the same lines above. Even when i try to reinstall it, it runs through the installation without finish sign and ends up with uninstall sign with the same problem.
    Thanks in advance for any help.

    1. I think you will have to contact CSR support for this.

    2. That will produce ZERO results.
      CSR has got one of the most unfriendly supports on the planet.
      And btw, Harmony is an End of Life (discontinued) product, and they do not offer any support for it (not even an unfriendly one).
      I would suggest to install Harmony again. The new installation would overwrite the old one adding the deleted uninstall file.
      At that point you will be able to uninstall from the control panel "programs and features".

  36. Hi Jesse.
    Thanks for your effort to promote aptX.
    I bought AZIO BTD V401 together with Harmony CSR stack (version Feb. 27th 2012). No probleme to install software on my Asus Windows 7 notebook. Besides the AZIO SB dongle is recognized but as a "Bluetooth radio" which means a Bluetooth receiver. Consecutively it is not listed as an output audio peripheral device in the Audio tab (I had not this problem with a Creative D1 USB dongle). How can I declare to Win 7 that it is an output audio controller?

    Best regards.

  37. Like many here, got frustrated with the CSR Harmony software that refused to pair with my brand new Samsung Level On Wireless Pro headphones. Despite repeated reinstallation and trying out various tips, the Audio Renderer either did not show up, or showed up as disabled (under Playback devices). Now I am thinking of switching to Bluesoleil 10. Does anyone know if it supports aptx? And secondly, how do I know if aptx is active -- is there a popup that shows up?

  39. A nearby look and nitty gritty perception will demonstrate that the retail administration framework programming in the cloud is under more security than one could have without anyone else's input in similar expenses, also alternate advantages. have a peek at this web-site

  40. Installed CSR stack on Win10 Pro x64. Did not think it worked due to runtime R6034 error, but rebooted, paired headphones via system tray icon and checked: driver used is version=2.1.63.0. When I connect to my Plantronics Backbeat Pro (supports aptx) the CSR APTX logo pops up. I use Bluetooth audio renderer in Foobar. The sound quality does not sound noticeably better than when I'm playing the music from my phone which I'm pretty sure does not support aptx (Xiaomi Mi5). I will have to do more testing.
