I've got Ubuntu 12.10 running on a Vizio CT15-A2 laptop. Everything was working great until I wanted to watch a video on a tv, I plugged in the HDMI cable, watched the video on the tv, and then unplugged the cable.
Since then the only sound that has played from the os is the start-up drum sound.
Ubuntu still recognizes the hardware, ie.returns the correct devices.Code:aplay -l
The sound settings box now doesn't list any devices to choose from.
Is there something totally obvious that I'm missing?
Please ask for any additional info that I can provide.
