System: AMD 400, STB LightSpeed, SoundBlaster 64awe. AT&T cable atlanta
Georgia. Debian Sid. kernel 2.4.2.
I have a STB LightSpeed 128 (BT848A), and I've been having troubles
getting sound to work. I've tried every single permutation of card=N and
tuner type=N and tvaudio options. Currently I have bttv card=3 and tuner
type=2.
I can't, for the life of me, get audio working properly. If I set the
tuner type to type=6 (Temic NTSC) and loaded msp3400 (which I did on a
lark) I got 20 channels (centered on the last channel I watched in windows)
w/ sound. If I set card=3 and tuner type=2 I get all the channels and
no sound, not to mention an odd annoying buzz when I move the mouse around.
This is what is being printed in /var/log/messages when I load the
module:

To me this seems that it found the tda9850 device and wants to talk to
it. But when I startup xawtv (or scantv) I get no audio. Following the
info in the file
/usr/src/linux/Documentation/video4linux/bttv/Insmod-options I tried to
forcibly tell it to load the tda9850 driver by going tda9850=1, that
didn't help.
Here are the relivant bits from my /etc/modules.conf file
--snip--snip--snip--/etc/modules.conf--snip--snip--snip--
post-install bttv modprobe -k tuner
post-remove bttv modprobe -r tuner
alias char-major-81 bttv
### update-modules: start processing /etc/modutils/bttv

### update-modules: start processing /etc/modutils/tuner

Please help a brother out, I need to watch my cartoons. :)
