  Ok, I've made a fair bit of progress, I can now get the
tuner to tune channels properly. Thanks to all who helped. It
was my own stupidity really, I had the freqtab=us-cable in
the .xawtv's [defaults] section not the [globals] section. That
and I had to learn to hit the cursor keys in xawtv. ;>

  Now my problem is getting the sound.

  With bttv, I can get the channel sound to come out of the 1/8th
inch jack on the back of the card. Not exactly what I want, but
it's a start.

  However, I am unable to get the sound working from the
tuner at all when using bttv2.

Background:
- Linux 2.4.16
- BTTV2 driver is from
http://bttv-v4l2.sourceforge.net/download/driver-20010625.tgz
- I am using bttv2 because I want to use mp1e, which seems to want v4l2.
- Card is a Hauppauge Wincast/TV, with a TDA9850 chip visible. This 
  is a bt848 card, not a bt878.

  In my muddling around, I was able to do a few things that seemed
to at least detect the audio chip. The following module installs
were done in the driver-20010625 directory:

insmod tvaudio.o tda9850=1

...gives me this in dmesg:

tvaudio: TV audio decoder + audio/video mux driver
tvaudio: known chips:
tda9840,tda9873h,tda9850,tda9855,tea6300,tea6420,tda8425,pic16c54 (PV951)
i2c-core.o: driver generic i2c audio driver registered.
bttv0: i2c attach [tda9850]
i2c-core.o: client [tda9850] registered to adapter [bt848 #0](pos. 1).

  Then:

insmod tvmixer.o

...gives me:

tvmixer: debug: Philips NTSC
tvmixer: debug: tda9850

...and that's about all that seems to make sense.

  Really, I'm just playing around though, I'm not sure exactly
which modules I actually need for sound so the above might be
totally offbase anyways. Is there a sure-fire process to get
sound working on this card?

  My eventual goal is to use mp1e to record audio and video
from a tuned channel, so I need to be able to get sound from
the tuner available to other apps. Does this need to be wired
to another input on my sound card?

  Thanks for the help. It's weird to be a newbie I've ran bttv
under linux for a half decade but this is my first tuner...
