I think its an ALSA bug, or the fault of the hardware driver. With my second
ALSA 0.9/1.0 patch I had 0%ish usage. But Elias had high useage. Then he
applied a patch that fixed it for him, and now I have high usage, so it could
very well be my via82xx drivers reacting to some odd alsa mode that allegro
wants. (I also think that allegro isn't setting all the setting it should
be.. theres a ton of hw and sw settings that other code uses, that we
don't...)
