AC97 sound fix
I am running Kubuntu Dapper on AMD_64. I just upgraded from breezy, where my sound worked fine. After upgrading to dapper, my sound went really low and static-y. I had sound, but it was really really bad sound. I tinkered with alsa and artsd, I checked all my connections, googled, tinkered more and finally I opened up kmix and noticed 4 sliders labeled VIA DXS.
Sliding the first one up fixed my sound issues instantly. The other three did nothing.
So, if you have a low static sound from your speakers, try the first slider in kmix called VIA DXS. I found nothing about this on google, so if nothing else works it may be your problem.
I hope this helps.
