I wouldn't think the mixer setting would have anything to do with recording 
the line input on the PVR card. The PVR embeds the audio into the MPEG that 
it creates, so mixer settings would matter for playback, but I wouldn't think 
they would matter for recording, that all happens on the PVR card itself.

Nor would I think you should hear the audio while recording, unless you were 
watching live TV, which is really just a simultaneous reocord and playback.

The mixer's "line" input shouldn't have anything to do with the line input on 
the PVR card.

I record a satellite receiver using a PVR-150, and I never hear any audio 
while recording, nor would I expect to.

What does "aplay -l" tell you about playback hardware devices?
