As the title says, I just installed Ubuntu 12.04 on my laptop using wubi, and I have no sound. $ pavucontrol shows sound playing, but nothing is coming out through speakers or headphones. You can access my sound information there.

Sound has worked previously with Kubuntu install on the same machine, and works fine in Windows 7. Please help!

run alsamixer and see whether the master volume is low – Web-E Jun 27 '12 at 4:11
@Web-E I've checked alsamixer and everything is turned up and not muted. – lachy2901 Jun 27 '12 at 6:34

You can reinstall the OS again. Had same problem once. Tried many solutions, like reinstalling alsa, changing the Alsa configuration file etc., restarting audio management service. But none worked. I just reinstalled the OS and it started working. so try it. Thank you.
