sound trouble on tvtime with a PCTV card based on Conexant Fussion bt 878a chip
My distro Fedora Core 5
Using Gnome 2.14.1.1 desktop
Nvidia Gforce 4mx 4000 graphics card (if it matters)
Running TVTime 1.0.1-3.2.i388
NTSC cable USA
Tv card is a Pinnacle PCTV based on Conexant Fussion 878a chip
sound card is a Sound Blaster Live
using alsa-lib 1.0.11-3.rc2.2.i386
I have included as much info as I could. Ant help to resolve this problem would be very appriciated.
I have read the man and info pages, but couldn't find it useful to resolve this problem.
The problem is with the sound. On startup the picture comes in great. The sound comes in as fuzzy kinda static with out any reconizeable audio. The audio is hooked up with an external cable to my line in on my sound card. Mixer volumes are all the way up. The odd thing is that if I goto channel managment and fine to aroung +10-12 I get poor audio quallity, and terrible picture quallity. Then I change the channel, and go back to the channel, Tvtime does not pick up a signal till i reset the fine tune to 0. Is there some kind of offset for audio tunning vs. video tunning. Or is there some other way to get the audio to work.

I have a completly different environment so use with caution.
IIRC TVTime is kind of Wine based and can cause all kinds of trouble. Give KTV a try.
Furthermore, did you check that you selected the correct Input for your audio. Just pulling up all input levels doesn't mean that you will hear it if that particular input is not turned on.
I also realized that your driver reports
[..]
bttv0: i2c: checking for MSP34xx @ 0x80... not found
bttv0: i2c: checking for TDA9875 @ 0xb0... not found
bttv0: i2c: checking for TDA7432 @ 0x8a... not found
[..]
so you aren't using a driver that decodes the sound data.

Looks similar to yours. In the mixer settings, I have to change to 2 channel mode to make it work. In Kmix, it's under the Switches tab on
my box. After I close TVTime, the sound doesn't stop until I change it back to 6 channel mode. Maybe someone else has a better way...
I have tried KTV in KDE and still get the same problem with the audio. I can adjust the fine tunning to get some poor audio while greatly reducing my picture quallity
I will look into this
bttv0: i2c: checking for MSP34xx @ 0x80... not found
bttv0: i2c: checking for TDA9875 @ 0xb0... not found
bttv0: i2c: checking for TDA7432 @ 0x8a... not found
And see if I can find something out.
Thanks for the link, I did not have this one.
AFAIK, poor picture quality in tuner cards often happen because of a low powered cable tv signal.
My understanding is that TVs might have signalboosting circuitry in them, but TV cards do not have.
To test the real pic quality, that your tuner card can produce, use a Video game console or a DVD Player
Have you tried to select a different tuner? The dmesg output shows it's using #33. For me, when trying to get my saa7133 card to work, I had to manually select a card and tuner to get it to work properly. Even though I have a NTSC card and tuner, I have to use PAL card selection and a different NTSC tuner then the autodetect uses to get it to work.
Try using different combos and see if you get any changes (even if worse). If you do, you know it's a driver (tuner/card selection) issue and not your soundcard/volume issue.
CARD #'s from the 2.6.15.5 Kernel:
39 -> Pinnacle PCTV Studio/Rave
52 -> Pinnacle PCTV Studio Pro
94 -> Pinnacle PCTV Sat
