Not much, other than [if it does follow my hunch] it should consistently work as expected on 7.x (with sound and snd_hda built into the kernel, sound built into the kernel and snd_hda built in as a module, and both built as modules). A bunch of stuff went into sound(4) in 8.x to 'improve sound quality' and it caused potentially non-deterministic breakage, but I don't have a concrete root cause for the issue (and haven't tried 7.x in a while); I did reproduce it by running as many instances of audio consuming apps as possible (haven't determined the salient number, but with 8 vchans, running 4~8 instances of vlc unrooted the issue on my 8-core box). I need to try reproducing it with snd_hda as well... Thanks, -Garrett
