So, Ubuntu 11.10 is still disappointing me. Now, my sound disappeared. Nothing in VLC, nothing in other players. What should I do?

We need more hardware information to help you, can you look at this question and then edit your question adding the information? – Jorge Castro Dec 1 '11 at 1:23
I am having the same issue. After upgrading to 11.10, there is no sound coming from any jacks. – Aras Dec 8 '11 at 6:59

I noticed that, out of the box, Ubuntu 11.10 has the sound control panel muted. You have to unmute it and turn the volume slider up to "10" (or 11 because its 1 more than 10)

Yeah I noticed that too, not sure why it happened kinda stupid if you ask me. Maybe it was an oversite that they missed before burning the final disc image? – TheXed Dec 6 '11 at 23:36
If that's the case, then perhaps a bug needs to be filed. – Christopher Kyle Horton Dec 7 '11 at 1:45

You provide very little information so its hard to really know where to start.

if you upgraded. Try removing the .pulse folder in your home folder. If you didnt upgrade make sure that the volume level is up.

Sometimes the volume controlls are mapped wrong. Use the utility alsamixer from the terminal try adjusting different settings there to see if you can get sound back.
