Bluetooth audio complains about 0 channels on CoreAudio

Post by marcel »

Since a few weeks I'm using bluetooth headphones on my Mac Mini M1 (fully updated to 26.6). They work in all apps, only in DoM (2.18.45) I get the following error:

I already searched for this error, with advices like disabling and re-enabling Bluetooth, stopping `coreaudiod` and deleting com.apple.audio.DeviceSettings.plist and com.apple.audio.SystemSettings.plist in /System/Library/Audio and restarting the system, but so far nothing seems to help. The only thing I got when I once forced-stopped `coreaudiod` was an error after selecting the headphones, stating that there was a negative number of audio channels (which I should have screenshotted, but I didn't).

Is there anything you recognize about this issue?
