Hi All,
I have just switched to Ubuntu 8.04 from Fedora Core. I always had a problem with my old TV tuner card in Fedora. It works great now. However, I have to swap the speaker cable from the sound card jack to the tv card jack to listen to TV. Also, the sound from the tv card just streams out, without xawtv or tvtime running. Is there a way to fix this so that the audio from the tv jack is input to the sound card and only output when a xawtv or tvtime is running? The sound is on-board, btw. Thanks,

Without knowing what tv card you have I am just guessing and making suggestions:

1. Run a small jack lead from your tv card to your line in?

or

2. Check to see if your tv card has a digital audio output connector on it (actually on the card) and that your motherboard has a connector too. Then use a cable, like the ones for connecting up CD-Roms. I do this with my card to get sound.

also sounds like something is starting up in order for sound to be coming from the tv card without you running an application. Try checking with top or system monitor to see what might be running, or have a play with alsamixer/pulse mixer.

THanks for the help. I think a little more info may help...

Only the on-board sound card shows up in alsa. Obviously manipulating any of these does nothing to the tuner card.

The card is an old All-In-Wonder card (circa 2000). Ubuntu identifies it as having the bt878 chip. It has coax cable in, composite in, and a simple audio jack out. I don't think it supports digital audio. It might have an output on the board in the case, but I haven't checked.

If the audio is streaming while tvtime is not running, its because its not auto muting the line ine when you close the program. I saw that several other people were having problems (as well as myself) so I posted a fix http://ubuntuforums.org/showthread.php?p=6445498#post6445498

Hope this works for you.
