Can we infer from this that this is a PVR-250? If so, the
HOW-TO instruction for recording from line-in don't apply.
The audio is multiplexed in the hardware encoding stream.
Either your driver modules are setup correctly to capture
audio (more likely) or PCM and Master aren't set to play
the audio (less likely). Others who are using these cards
may be able to give you more specific advice.
