Configuring VT8233 chipset audio

I jus downloaded Knoppix v3.6 today and it detected every piece of hardware on my comp (Cheers to those guys working at Knoppix)...but my soundcard seems to be a problem...The driver it has chosen via82cxxx_audio doesnt seem to work...I read on the Knoppix site that there is a problem when it comes to vt8233 and configuring it for linux...but the thing is my sound card worked under Mandrake 10.0 Community edition under the Open Sound System and the driver there was snd_via82xxx .. So can someone direct me as to how i can configure my sound card? and can i change the driver to snd_via82xxx? if so where can i find the config tool?

Here's the full output of lspci -v

but the thing is my sound card worked under Mandrake 10.0 Community edition under the Open Sound System and the driver there was snd_via82xxx ..

---

i am surprized... for me snd_via82xx is the ALSA module,and via82xx the OSS one.

pls try knoppix with cheatcode ALSA=via82xx

use kmix, help, hardware info (or something like that, I have a french version) to check if you use OSS or ALSA.

i checked in mandrake .. it uses snd_via82xx under OSS and sound works fine...can i possibly change this option during booting instead of it autoconfiguring to via_82cxxx?

Go to Control center---->Sound & multimedia-->Sound system---->Hardware
---->change autodetect to Open Sound System---apply.

I maybe a new user...but i did all what you said...it only worked in Mandrake...doesnt work in Knoppix

Okay...I never said you a newbie. :D
For me..everybody is a newbie when it comes to linux.

Lets try with alsa.
Run this command in root konsole: /etc/init.d/alsa-autoconfig
See if your card is detected and configured.
Configure as my last post, change autodetect to Advace linux sound architecture (alsa)
Test if sound is produced.
If succeed, then run this command to make alsa configure everytime you boot: update-rc.d alsa-autoconfig defaults

Good luck

:D :D

Tried it....doesnt work...however is there a similar command for oss (like oss-autoconfig or something)...also where are the config files for sound present, under what filename.

Have you try booting knoppix cd with cheatcodes: knoppix alsa

:D

Yes, I tried with knoppix alsa and even knoppix alsa=es1938

Both doesnt work

Then lets do all this in root konsole:

modprobe snd-via82xx.ko
modprobe snd-pcm-oss
modprobe snd-mixer-oss
modprobe snd-seq-oss
update-modules

Then run lsmod to see if sound modules is loaded.
Reboot.
Run Kmixer.
I believed alsa won't work with your mobo.

:D

Still doesn't work...i get a "can't locate module message"

Sorry, it's not modprobe snd-via82xx.ko
but modprobe via82cxxx_audio

Code:

---

modprobe via82cxxx_audio
modprobe snd-pcm-oss
modprobe snd-mixer-oss
modprobe snd-seq-oss
update-modules

---

Good luck :D :D

Still doesn't work...

Sorry can't help anyfurther but you might want to read this, someone has solved the problem. He found out that the sound card is conflicting with onboard modem. By disabling the modem in bios, the sound card works.

And this how the soundcard is set in redhat:

Good luck, let us know if it works.
