[linux-audio-user] SIS (SI7012) fails under jack

Hello i have si7012 onboard soundcart, which runs without any
problems under alsa.
But doesn't work with jackd.
Sofar i don't get a error from jackd when starting, the jackd runs
smotly and accepts also input from application,
Alsamixer shows also that master and pcm lines are up.

The soundcard works with alsa but not when i use jackd so i guess the
problem is related to jackd, what makes no sense to me since i think the
alsa API
should be totally transparent to jackd regardingless which soundcard is
used.

Any idea what could be my problem?
