I just installed ubuntu 11 and my sound isn't working. More specifically if the sound is all the way up I can hear very faint noises.

I've read around and this seems to be a common problem historically, but none of the fixes are working for me. There appears to be a similar question already out there No sound on a realtek AC97

I've ensured that my volume is up in alsamixer from this thread

I've also tried this fix from the guide, with no luck.

I've tried to update to the newest alsa drivers, but also no luck. This post from 2007 even suggested downgrading to a different kernel rev. I am tempted to try it, but there has got to be a better way.

Please let me know if there is anymore information that I provide.
