Please don't assign subtype, this is up to developer to decide.

Also I assumed this was already triaged because of this.

Some background on the problem here:

https://forum.snapcraft.io/t/reusable-alsa-lib-part/3556
https://snapcraft-alsa.readthedocs.io/en/latest/index.html

Basically, only PulseAudio is available by default, and require some fiddling with environment variables to work.

ALSA and OSS are not available and trying to use them seems to block sound in other apps. There are some ways to make ALSA work by bundling our own build of the ALSA library, but that seems overly complicated. We now just rely on PulseAudio working for sound and explicitly disable ALSA and OSS.

Is the fix going into the next release? or will the snap package be patched?

It will be fixed in the next release (2.83).
