I was watching a video and everything was great. Then I accidently clicked on the screen and the sound quit working and I couldn't get it to work again. I tried with the mint system  settings and I tried with alsa mixer but nothing worked. In my googling I found the suggestion to add 'options snd-hda-intel model=generic' to alsa-base.conf but that didn't help any. The sound kinda works because the system alert noise (I have it set to bark) sounds.
