Everytime I try to use any bluetooth headphone together with VoiceMeeter I get an error message right after selecting the device:
Output Device not Working...
Failed to Open Main Output Device (A1)
Device not ready or used by another process. Select A1 Output Device first!
Keep default settings (default buffer size).
Device configuration might be 32, 44.1, 48, 88.2 or 96kHz only
pAudioClient->Initialize return error -2004287480
(0x88890008)
Selecting the headphones as the output device directly via the Windows Sound Settings works however. They will play sound and work as expected, but when switching back to VoiceMeeter and selecting them there, I will get the same error.
I tried looking up on how to check which program uses a certain device, and found this thread. However, I could not find any other program using the headphones.
.
When following the prompted
Select A1 Output Device first!
and selecting a working output device for A1, then the A2 for the headset, the error message will not appear, but output will still not work.
I am using the latest version of VoiceMeeter Potato:
Windows 11 Pro Version 10.0.26200 Build 26200 x64
Officially licensed VoiceMeeter Potato Version 3.1.1.9
Tested with Teufel Supreme On and Teufel Real Blue NC
