Hi,
It is possible via an .asoundrc but you wont get it to
work
with jack without xruns. xruns are when one soundcard needs
its new data (for playback) before the other card. It
happens because your soundcards won't run with _exactly_
the same frequency altough all clame to to 44.1kHz/48kHz.
short question: Is this also the case, if I have three cards
but only one is used by jack?
I also get xruns with my USB card. It's the third card,
because I have an AC 97 and an USB2MIDI device.
When I try to run jack, it works, but I get some (but not too
much) xruns. Should I disable the AC 97 card?
Thanks & best regards
