Strange... I know on my AA1 for example with HDA - running the Big Buck Bunny video (480p) while loading up the CPU doesn't make audio glitch (at least not until I add enough load to make the video glitch as well). Perhaps it would maybe be worth aggregating some useful information (i don't know which info, and please not in this thread) among people who have issues and those who don't to see if there's a pattern that can be used to track down the cause.
