[ubuntu] installed/uninstalled lubuntu now I have very bad sound

view story

http://ubuntuforums.org – I installed lubuntu to see if I liked it. I have an old Acer Aspire 3000 and thought it might help. Installing lubuntu has destroyed my sound. In ubuntu sound was good enough to stream lastfm at a decent volume. Now it seems like the volume has been turned up so much the speakers just give static. I dont know how to correct this, I have turned volumes down in alsa but that doesnt seem to change anything. Please help (Hardware)
