[SOLVED] Sound disappeared, get static on laptop

[LeeLgrqst]

I have a Gateway mt3422 laptop. I just moved from Windows Vista to Ubuntu 8.10 64, so I am just starting to learn how to use this OS.

So when I first installed it, the sound worked. Then one day I went to play a CD and discovered that the sound didn't work anymore. The only thing that happens is a crackle sound coming from the speakers.

I tried this, which I found in another post from this site:
sudo killall pulseaudio
sudo alsa force-reload
and then go to System>Preferences>Sound and change everything to ALSA

It didn't work. I've been searching for days on how to fix the problem, but I don't know what to do.

Solved - I found this in another post finally.

I had to right click on the speaker icon on the panel. Click on the Open Volume Control and turn up the PCM and Capture Mux.
