Nikolay, thanks for opening a bug here, is it possible for you to provide the information I asked on github, alongside a copy of the "raw data" of about:support, so we understand a bit more your setup ?

Nikolay, thanks for the debug info. Would you mind also attaching the output of running pactl list while reproducing the problem so we can get an idea what's going on with the buffer configuration of the sink and source? Thanks!

Sound recording in version 128.0 still doesn't work properly (sound sometimes just doesn't record), the only perfectly working backend is jack.
