Hi Clemens,
I fiddled around with the Dummy module and it seems to be the thing we're looking for. I observed a rather strange behavior though:
I set the hw params sample rate to 44k1 without error, but a subsequent call of snd_pcm_start returns EPIPE. When setting hw params sample rate to 4k this does not happen. Did I miss anything?
Regards Uli
