Re: [Trisquel-users] There is No Sound After I Installed Trisquel! How do I Restart the Sound Service?

On debian Jessie I had this issue with pulseaudio, which is apparently a huge  
crap as I know from direct experience having it tested on several different  
hardware. My fix is purging pulseaudio entirely and using alsa, alas alsa is  
great \o/

You might want to keep pulseaudio though..
Try this and tell us if it worked ->
