oh thanks, that's good to know.

this means that ac97 is not routed as audigy1. perhaps a different
bus is assigned.

what kind of output is expected on this jack?

this might be a bug of the driver, but not sure, atm.
could you check whether interrupt counts increase when you receive a
midi input?

hmm.. it seems that on audigy2, ac97 playback volumes should be kept
zero.

thanks for your tests!
perhaps i'll get audigy2 for tests, too, and will take a deeper look.
