I had a similar issue.  I'm using a PVR 250 and capturing the s-video 
and line-in inputs.  I had to issue the following command (found on the 
list) to capture sound from line-in and not the tuner (at least that's 
what I think it does):

ivtvctl -v input=1,output=1

Not sure about your configuration, but might wanna check this setting.
