Clemens,
Each card is different.
Onboard chips are supposed to be AC'97 compatible, so you
can look into the AC'97 specification to find out what your
chip doesn't work like.
If you have luck, there is a datasheet for your codec chip.
thanks for your hint.
I'd like to mix my Terratec Aureon USB.
Meanwhile I noticed that the GUI of qamix can be configured
using xml files, so I'll try it out. Currently, it only shows
one control, that's a bit less ;-) .
I expect to be successful, so qamix will give me a better
control over my card.
BTW: I also googled to find a nice image showing the signal
flow of AC97 cards, but I haven't been successful. But the
AC97 is not that important at the moment :) .
Best regards
ce
