I have no doubt that it was but it didn't answer my question in terms of the card being able to feed the audio section via system bus.
Some cards need to be cabled but some cards have the audio on the bus so just sends it directly to the sound card. Well, then again, I believe that's how some of the cards I've owned have worked.

Yes I've read that and also found references to this in forums where people were talking about unloading, reloading.

And as I understand a pvr, everything you watch is always being recorded moments before you're watching it, hence, rewind, forward, record, etc.

I'm missing something then. I've gone through all of those menus and can't find a thing on setting up the audio. 
Must be buried in there somewhere then. I'll go look again.
