I'm slightly confused about what audio support *should* look like.  When
I modprobe cx8800, I get the following:

# modprobe cx8800
cx2388x v4l2 driver version 0.0.4 loaded
cx2388x: snapshot date 2005-01-20
ACPI: PCI interrupt 0000:01:08.0[A] -> GSI 16 (level, low) -> IRQ 16

cx88[0]/0: cx88: tvaudio thread started

I did (once) get a successful sound through the line-out of the WinTV
card and through the line-in of the sound card, but that's stopped
working.

Also, the tuner was detected as a new TAPC sort once, but that's
stopped, and I can't figure out why it stopped doing that.  (I believe
that was when the card worked fully with colour and sound).  Can I
override this?

Modprobing any other modules (such as tda9887) with any options doesn't
have any effect, and I don't see any chip found.  

Is there any way of using the internal audio decoder on the conexant
chip so that I don't have to use the line-out to line-in thing?

This is all using the 20040120 snapshot (I can't compile the 20040124
snapshot on my 2.6.10 kernel).  I'm in the UK trying to use PAL-I.

thanks,
