hi all,
i've got a problem with my brand new hdsp multiface / cardbus ... i got
everything working so far ... modules are installed and can upload the
firmware ... i can even use the hdspmixer to mix the incoming sounds to the outputs
...
but i didn't manage to play any sound from the computer ... i can
start jack / pd / spiralmodular, but all i hear is a distorted sound,
that sounds a bit similar to what i expect the signal to sound ... the
pitch of the distortion changes when i change the rate of the
sample clock source ... any idea what could cause this behaviour ?
btw, i can't start jack when i set the sample clock source to values
greater than 62khz ...
the strangest thing ... when starting the audio application, the output
signal that is routed from the input channels has these distortions,
too, until i stop the application...

Hi Tim,
There clearly seems to be a problem with your setup whenever the card generates audio IRQs, but I can't think of anything at the moment.
Could you please give more details, namely :
* the output of lspci -vv
* the output of dmesg
* the contents of /proc/asound/cardX/hdsp where X is your hdsp card number
Now regarding the clock source problem, if you want to start jack with a sample rate higher that 48000 you must first select the appropriate sample rate with hdspconf or amixer, then start jack specifying the desired sample rate on the command line.
