Kubuntu 6.06 No Sound.....VIA 8237


Hi.

I'm looking for any help I can get regarding getting sound from my mobo's built in VIA 8237 AC97 sound chip. The chip does work great and is set up properly as verified when booting into XP. I've decided to try out desktop linux again (after a 2 year hiatus), but now I cannot for the life of me manage to get sound out of this card.

Kubuntu did a great job of detecting the VIA8237, and happily tells me that all is well and good when the mixer is viewed. I've also run alsamixer to verify nothing is muted.

I'm definately a linux noobie in so much as I can edit config files, but not really troubleshoot them. Does anyone have any insight or help to offer?

Thanks.
Rob.

It's an Asus A7V8X-X mobo with onboard VIA sound. Last time I checked ALSA all the VIA soundchips use the same modules.

How does this compare to yours?

Thanks for the reply Chinaman,

I'm running a Soltek KT8Pro-939 motherboard, also with onboard sound (ala VIA8237 AC97 type). I ran a comparison, and it seems to be pretty close to what you have, although I have some other information showing as well which appears to be my connected Logiteck Webcam which has a built in Microphone. Either way, here's my results:


snd_seq_dummy 5508 0
snd_seq_oss 38372 0
snd_seq_midi 11456 0
snd_seq_midi_event 9984 2 snd_seq_oss,snd_seq_midi
snd_seq 64088 6 snd_seq_dummy,snd_seq_osidi_event
snd_via82xx 32936 1
gameport 19216 1 snd_via82xx
snd_ac97_codec 110268 1 snd_via82xx
snd_ac97_bus 4096 1 snd_ac97_codec
snd_usb_audio 92672 1

usbcore 145980 6 usbhid,snd_usb_audio,sndcd

bison@bison-desktop:~$ /sbin/lspci

Again, any help is greatly appreciated.

This could be the old sound card 0/1 problem if the camera microphone is treated as a soundcard

fair enough....and a good chance that's it. However, my problem then becomes a matter of how to fix that. Any sugestions or ideas?

Here's a thought.

It would seem as though Kubuntu is loading things as such:

/dev/dsp ----> USB Logitech webcam with microphone
/dev/dsp1 ---> SAA7134 ASUS TV FM Tuner PCI card
/dev/dsp2 ---> VIA 8237 Onboard sound

I've read others that have basically the same setup and have managed to force somehow the system into loading VIA 8237 first so that it lands as /dev/dsp and for some reason this makes the sound work properly. If this is the case, how would I go about changing the order these are loaded at boot?

Thanks,
Rob.

On Slackware module options can force the card order (search the Slackware forum here), not sure on Ubuntu

Update: I found a "solution". By opening my computer, I pulled out my TV card and unplugged my Web Camera, then rebooted. Kubuntu then FINALLY figured out my soundcard. I then shutdown, re-inserted my TV card, and there it was, working sound. I've not yet hooked back up my webcam to see if things stay fixed.

I say "solution" in so much as this is a terrible fix. At least it worked.

Thanks to all who tried to help.
