Kworld TV tuner card -- No sound!


I am running Debian and have a KWORLD TV878RF-PRO tv tuner but can't get any sound out of it. I'm using ALSA and a soundblaster live which works fine. I can't get sound out of the audio out of the kworld card at all. It works fine in win98. Any help would be much appreciated. Here are the outputs of lsmod, lspci and dmesg. Thanks again for any help.

if your card has a audio out that connects to a line in jack on your soundcard, make sure that input channel is not muted.

I've verified the line-in isn't muted by playing a cd player through it. I can't even get sound out when I hook the audio out straight to a set of headphones. I've tried everything I can think of so far. I know some are using this same card for mythtv so it can work. I'll keep trying.

KWorld Card

Try identifying your card properly when you insmod the bttv module. There is a list of which card is which in the kernel docs: Documentation/video4linux/CARDLIST.bttv

Mine seems to work with:
insmod bttv card=78 tuner=2 audiomux=0

And it's coming into Line in for sure now.

I just got one of these - I had to use an OSS mixer (the gnome-panel app ) to raise the volume on the tuner card - the ALSA mixer doesn't pick up the btaudio enabled card (using Mandrake 10).

I also have built in audio on my mainboard that redirects centre and surround to the microphone and line in ports. I had to "mute" those settings to get the sound working.


If you haven't solved the problem yet, hopefully this will help.

i ficed the problem with it

i have a asus tv-fm card with the saa7133 chip. what i have done was i put the card audio wire into the cd input and i got sound . so my advice is to check your connections and see if it still works if not go to linux.bytesex.org to see if there are kernel patches for your specific card . thank you for your attention
