My sound is not working. I am running Quetzal. I have the xfce desktop environment. The relevant drivers are nvidia in origin.
My speakers are on and plugged in. The green plug is in the green input. I have gone through Alsa and have made sure everything is unmuted.
It had been working for a week (just installed ubuntu a week ago). Then the other day the sound stopped working, and I fiddled with the alsa mixer for like an hour and then it started working again.
Then yesterday I couldn't get it working again at all.
