I even moved it to a different slot on the motherboard, with no results. I also deleted them in myth-setup and re-added them, still nothing. Channel change script is changing channels correctly, but no matter what sound is terribly distorted. I also switched the card with another one...Any help would be awesome...

Use alsamixer or something like that to check that you are not just overdriving the audio circuits?
It worked, and 'failed' after updating, so I would bet on it being the new settings.
