[Bug 29789] Re: tv card audio not working

[Josip Rodin]

Hi,

I have been experiencing the same problem on my bttv card there is no longer
any sound (it stopped working some time ago, I can't remember exactly when
and how). The bttv driver identifies it correctly as:
Terratec TerraTValue Version Bt878 [card=33,autodetected]

The TV card is physically linked with the line-in of the sound card.
The mixer settings are fine, the line volume is pumped up.
It doesn't appear to be a hardware problem because:
* if I plug the speaker system directly into the TV card I can hear TV sound
  normally
* the same audio cable worked just fine in Linux some time ago, and still
  works today in Windows

It's as if nothing is going through the line-in of this snd-intel8x0.
alsamixer describes it as:

Card: NVidia CK804
Chip: Realtek ALC850 rev 0

Maybe that's the actual culprit for some of these problems?

I backtracked and it's not working with kernel 2.6.21.1, 2.6.19.1, 2.6.18.
I haven't kept any older ones :/

I'm not sure if this is the right bug number, because here people are
talking about snd-bt87x. I tried loading that module, had to use the force
option, it said:

unknown card 0x878-0x153b:0x1118, using default rate 32000
please mail id, board name, and, if it works, the correct digital_rate option to <alsa-devel at lists.sf.net>

alsamixer -c 1 says there's a "Capture" setting, but I can't adjust
anything, so it seems pretty much useless to me.

I also hear that buzzing sound that the #38497 submitter mentioned, but that sounds like some sort of generic
TV tuner noise to me, that otherwise gets drowned when the normal TV audio is working.

I wouldn't describe the noise as 'tearing' (as the #29789 submitter
did).

Maybe these are not duplicates. #58969 mentions snd-intel8x0.
The submitter of #38497 didn't note his sound card - if it's also a snd-intel8x0,
then we may have a pattern there.
