First problem is here ^^^^^^^

Looks like this card is not explicitly recognised by cx88, so you need 
to tell it what tuner you have.

I seem to recall from an earlier post you had tried tuner=38, to get 
cx88 to use that , add the following to your /etc/modules.conf
options cx88xx tuner=38
Or, do the modprobes in the following sequence:
	modprobe cx88xx tuner=38
	modprobe cx8800
(after deleting any loaded copies of these and tuner).
You should then see a line like:
tuner: chip found at addr 0xc2 i2c-bus cx88[0]
tuner: type set to 38 (Philips PAL/SECAM multi (FM1216ME MK3)) by cx88[0]
in the dmesg listing if its worked.
tveeprom: tuner fmt = PAL(D/K) (eeprom = 0x50, v4l2 = 0x00000e10)
tveeprom: audio_processor = MSP3425 (type = 15)

cx88[0]/0: registered device vbi0
cx88[0]/0: registered device radio0
cx88[0]/0: set_audio_standard_BTSC (status: known-good)

This is the second problem - the driver is setting tv norm to NTSC by 
default.
cx88[0]/0: cx88: tvaudio thread started
cx88[0]/0: AUD_STATUS: 0xfaf2 [mono/no pilot] ctl=BTSC_AUTO_STEREO

and this is the audio setting for NTSC.
(aside - if you want to stop your log filling up with these messages, 
use the setting audio_debug=0 on module cx88xx, good idea when you have 
it working)
You need to explicitly set tv norm to PAL-I (not PAL - that will get you 
PAL-BG and no sound).
I use:
	xawtv setnorm PAL-I
but I have never used MytTV, so have no experience of how to force its 
norm settings.

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.

Try back tracking by undoing your changes to the point where it works?

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?

See above - your tuner type is probably not 38 if you saw this. Use the 
value that worked then.

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

cx88 sound started working at 20040120, so that is fine.
