Ingo:

The pvrusb2 driver does not have any interactions at all with anything 
involving ALSA.  Sound output is an application issue.  All that pvrusb2 
does is make the mpeg2 stream available from the hardware, and the audio 
within the stream is embedded by the PVR USB2 hardware itself - therefore 
the driver never actually directly touches a pure audio stream.  Hope that 
helps clear the air a bit.
