Hi Lennart, Thanks for your suggestion.  However passing mmap=0 to module-alsa-sink doesn't bring me any luck to make it work. I will report this to ALSA people.  On the other hand how can I get more information from PA to pass to the ALSA people?

The plughw module doe not seem to be able to properly reformat the audio data as needed for PA. Please report to the ALSA people. This is most likely due to some mmap/non-mmap conversion bug in plughw or so. Try if things start to work in PA if you pass mmap=0 to the alsa sink module. Also, please note that under almost all circumstances passing plughw:0,0 is wrong. You should not specify the subdevice. Use plughw:0 instead.
