Title:
Broken audio capture subsystem
Status in Ubuntu MATE:
New
Status in linux package in Ubuntu:
Confirmed
Status in ubuntu-mate-meta package in Ubuntu:
New
Bug description:
In Impish the problem of capturing audio by discord (from app or browser does
not matter) when broadcasting reappeared.
The window is being captured or not - it doesn't matter.
It looks like a regression.
Webcamoid don't capture sound from micro too.
If I set gstreamer method instead of ffmpeg 4.4 then sound appears, but very
laggy
Discord launched in a browser and streaming an adjacent tab does the same.
I don't even know what to report on. Looks like a broken audio capture
subsystem.
ffmpeg -f alsa -i <record device> -t 30 out.wav and ffmpeg -f pulse -i
<record device> -t 30 out.wav captures sound normally.
