I tried enabling msi on alsa and its alot better. Still fulscreen is not good, but much sounds like 11.04

Add: options snd-hda-intel enable_msi=1" to the bottom of your /etc/modprobe.d/alsa-base file.

I think radeon is somehow not playing nice with msi. If we could disable it it might fix the problem...I tried doing it with echo 0 > msi_bus in the radeon bridge but it wasnt working
