No - that's not quite right.  The problem is specifically with audio in FM
mode:

I get audio from the "digital" btaudio device when the WinTV is tuned to a
TV channel, or set to the Composite input.

But I get no audio when the card is in FM mode.

I've appended a patch that seems to solve the problem.
