Had to look for name two or three times too Nathan....
On Ubuntu launchpad audio bugs abound... And one similar/same bug when Intel HDA part of the puzzle.
Bug: #704206 Rampant audio corruption
Ref: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/704206
I also see specs for GA-MA78GM-US2H motherboards show onboard audio is Realtek ALC889A (not the identified Intel Azalia).
Still unassigned probably due to the half-workaround. Somewhat promising work-around.
