bttv sound vanished (alsa+2.6.5 kernel)

hey all,

i had just gotten my tvtuner card up and running (ATI TV Wonder), and the picture was fine and i had working sound.

i dont know if it was something i changed, or something that i had loaded, but when i reset my box, the sound stopped working on the tv card, and i havent been able to get it back, but the video is still okay. i have read many posts on these forums about unmuting the "line" control in the alsamixer, but i tried that with no luck... also i am a bit confused how the tvcard uses the "line", because isnt that an input from one's soundcard? i think i am confused, but are people running a cable to their soundcard from their tv card? ...i dont think so, but it just seems odd that the line-in controls the tv tuner audio.

anyway, i really cant remember if i loaded any modules previously that may have gotten the tuner card sound. is there some type of history or something that i can check to see if i had something loaded besides what is in my kernel-2.6 file?

as for some specifications, my sound card uses the cs46xx driver, which i built as a module, and my sound from xmms works fine.

relevant lsmod:

yes people are running a line from there tv card to their sound card... thats what i have to do. I have the cheap version of your card (the VE) and there is a small wire that goes from the tv card to the line-in port on the sound card. I know that some cards do not need this line.... I think the btaudio module is used for instances such as yours.

Anyways, I had a similar problem as yours and I was able to get sound by turning up the "analog mix" and "line" in alsamixer. Hope that helps.

thank you for the reply.

yea, i have gather people are running cables from the tv tuner to the sound card, however i didnt do this before when the sound worked... it is very odd. maybe the card was horribly messed up and now it is working "properly" (with no sound).

but i do have the audio out in the back of the card, and i tried to hook up headphones to it... which should work since it is analog (i think), and i didnt get any sound.

i am curious how you "turned up the analog mix" in the alsamixer... i have "Mix", "Mix 1", "Mix Mono", "Mix Mono 1" and i tried

well, i am getting nowhere with this sound issue... it seems to me that something is just muted, because the card is being detected and operates fine (without sound of course).

but is there a way to unmute, or control the volume of the ATI Wonder card itself? i have been reading on other posts that you can adjust it via the Mixer. can someone please explain this? it seems like the audio output from the tv tuner is just off... or something.

thanks
