XAWTV no sound

Hi,

I've gotten xawtv running but seem to be unable to get the sound to work, no matter what I do. I know /dev/dsp works since I can use it with xmms. All sound as well as video modules are loaded. I tried 'xawtv -C /dev/dsp' but nothing. My motherboard is a SuperMicro P4DC6 which has an onboard sound controller which uses i810_audio and ac97_codec. The Video card is a Hauppauge WinTV-DBX, Graphics card is PNY GeForce4 MX440.

Loaded modules:

tuner 10500 1 (autoclean) tvaudio 13536 0 (autoclean) (unused) msp3400 16720 1 (autoclean) bttv 72992 0 videodev 8128 3 [bttv] i2c-algo-bit 9196 1 [bttv] i2c-core 21984 0 [tuner tvaudio msp3400 bttv i2c-algo-bit] i810_audio 23424 0 (autoclean) ac97_codec 12608 0 (autoclean) [i810_audio] soundcore 6820 2 (autoclean) [bttv i810_audio]

Anyone have any suggestions?

TIA,

Nothing else is using /dev/dsp and the mixer shows that nothing is muted. I closed programs using /dev/dsp before running xawtv.

Disable sound in your desktop? If checked it will share the dsp device. Well that is a poor choice of words. If you are using kde and have desktop sound enabled only apps that manage sound through those libraries will ALWAYS be successful. An app like XMMS will only have sound if the desktop is not trying to play something. Classically people have an opening window play a sound thus when XMMS tries to get the device it is busy. XMMS (being an X app) is not aware of kde sound management. I believe XAWTV is the same can you confirm?

I don't think so. On my redhat 7.1 distro, xawtv never had a conflict with sound (though a program I wrote myself, which uses the old OSS interface does run into problems sometimes and I have to kill the process that's taken over dsp, I guess I need to make some changes in my program.)

Different video cards require different options values. For example, my STB card has to take the options bbtv card=3, and options tuner type=6, whereas my Zoltrix card takes options tuner type=6 and bttv card=15. If you are getting video then probably bttv is OK and the tuner needs tweaking. You might find some suggestions in /usr/src/documentation (or something like that, I don't have a source directory handy to check; maybe it's with a capital D, but that's a directory, you still have to drill down some looking for the sound

Have you plugged the TV card's audio output into your sound card? If not, then there's the problem. The TV card should have come with a small audio cable, which is meant to be plugged into your sound card's line-in jack.

Some additional information. Ichecked the logs and the msp3400 driver seems to recognize the chip as MSP3435G-B6. I'm running RedHat 7.3 with the 2.4.20 kernel, not from the RedHat update but from the kernel archive. bttv0 entry also shows tuner = 2.

Thanks,

Try it without the msp3400 sound module. When I first tried to set up my TV card, I was loading this module, and I got no sound. But when I stopped loading this, I got sound.

Are you sure it is correctly recognising the card? I had problems with this. Try specifying other card numbers when you load the bttv

I don't exactly know about your card, but mine (PlayTV Pro) was a real pita trying to get any sound of it. Magic came from the bttv_gpio and audiomux parameters of bttv module. For me it was:

bttv_gpio=1 audiomux=2,0,2,0

Actually I scripted around audiomux probing every combination of n_1,n_2,n_3,n_4 with n_i in [0,1,2]. As soon as I got actual sound, I wrote it down, and fall asleep :-P (there wasn't an 'unique' combination, though).
