Re: [Trisquel-users] No Sound After Trisquel Mini Install T60

Well, I don't know if this will help your case, but I remember an issue  
related to pulseaudio on the old Debian Stable (Jessie), in that the audio  
would randomly mute and whatever I tried it would not come back..

The pseudo-fix was to install pavucontrol and then unmute it within its GUI.
The real fix was: sudo apt purge pulseaudio.
