Bug

Only root and audio group can read from and write to files in /dev/snd.
My regular user account belongs to audio group which allows me to play audio.
nogroups option in mpv.profile and vlc.profile kills ALSA audio.

It seems that firefox-common.profile also contains nogroup option. This is going to break audio in firefox and librewolf, too.

Environment

Firejail version

$ firejail --version
