Issues when using same device for mic and background music output #251

Open harshita-gupta opened 5 years ago

harshita-gupta commented 5 years ago

I think there's issues that come up when using an external bluetooth headset for audio input and output.

I am using external bluetooth headphones (Airpods and Bose QC35) to video call with Zoom. I use Background Music to increase bluetooth audio levels.

The following set of settings scrambles the audio output to my headset (incoherent audio). Background Music output: Airpods Zoom speaker: Background Music Zoom microphone: Airpods System output device: Background music.

With the below, changed settings (I changed zoom microphone from Airpods to Background Music), no mic input is detected by zoom and the other call attendees cannot hear me. I'm guessing that background music is not transmitting input to zoom. Background Music output: Airpods Zoom speaker: Background Music Zoom microphone: Airpods System output device: Background music.

How can I fix this? Thanks.

I'm not sure what would be causing this. Your first set of settings looks right to me. I wouldn't expect the second set to work, though. The Background Music input device is just a loopback of the audio received by the Background Music output device.

It sounds like your issue might be related to #223, but I haven't been able to reproduce that one myself either.

Do you still get the scrambled audio if you set the volume for Zoom in Background Music back to zero (i.e. put the slider in the middle position)? Do you still get it if you use non-Bluetooth speakers/headphones?

It might be worth trying with the latest snapshot build of Background Music, if you're not already using it.

Is there any update on this? I'm having very similar issues

I have got the same problem, but just with a bluetooth headset. If I use a headset connected with am cable I don't get audio-feedback/backcoupling

I also have the same issue on the pre-version for Big Sur on a Macbook M1. Also tried with the non-pre version and it just crashed (as expected). I also reset the volume slider for zoom but to no avail.
