QCNCM865 (Qualcomm Network Card) On FW13 | Win11 | AMD 7040

I have had an issue upgrading to the Qualcomm Wifi 7 Card, bluetooth audio doesn’t work.

I reset the computer, updated bios, downloaded most recent driver package, did a clean install of windows for this testing.

As other threads have said, disabling AMD BT Audio Device, makes audio work. But, the issue I had is with AMD BT Audio Device disabled, Teams does not recognize the bluetooth device as an available input and I don’t hear anyone else in the call.

So, AMD BT Audio Device disabled = desktop audio works but teams does not.
AMD BT Audio Device enabled = Teams audio/mic works but desktop audio does not.

As far as I can tell so far, this is a Windows issue. AMD BT Audio Device is enabled, and I of course get no audio playback. But when I open the sound panel (mmsys.cpl) and switch to the recording tab, audio works perfectly. When I close that window, or switch to a different tab, audio stops.

Likewise, if I open the camera app, and start recording audio playback works. Stop recording and I can no longer hear audio.

So this tells me something in windows is causing the issue. Posting here to see if anyone else has a solution. If I find the solution on my end, I will update the post to include it.

Edit 1
Playback immediately resumes whenever an application actively captures audio from the Bluetooth microphone.

Confirmed with:

  • Recording tab in mmsys.cpl
  • Windows Camera while recording
  • “Listen to this device” enabled on the Bluetooth microphone

As soon as the capture stream stops, playback fails again after a few seconds.

This suggests the issue is related to the Bluetooth microphone (HFP) transitioning to an idle state rather than Bluetooth playback itself.

*Edit 2/3*
Installed OBS Studio. Setting my BT headset as default in OBS (audio mixer panel, Mix/Aux, Properties, select BT device instead of OBS using system default) Audio Playback works even without OBS actively recording/streaming.

(Edit 3 just fixed a typo)

Edit 4
Playback during any of the above mentioned scenarios is notably terrible - not at all what the quality should be. So… The only Bluetooth path that remains functional with the AMD BT Audio Device enabled is the hands-free/call profile?

To me this seems to be a hand-off issue? For whatever reason A2DP is not taking over stereo playback like it should… is what it seems like to me.
