I can't seem to find the thread right now, but this has been addressed
before.  You need to make sure that you set the HD-PVR for the correct
audio input through v4l2-ctl.  Assuming your HD-PVR is on /dev/video0,
first type v4l2-ctl --device=/dev/video0 -l to get a list of the
current settings.  If I remember correctly the "audio_encoding" needs
to be set to (I believe) 4, but I could be remembering incorrectly,
and I can't get to my box right now.

A search of the archives for "HD-PVR" and "v4l2-ctl" might get you the answer.
