soundcard detected, but mixer cannot be found

**jfhawk06** · 04-17-2005, 02:44 AM

hi, i've just upgraded to 3.8.1, and the only problem has been the sound (which seems to be a common problem). when i boot, knoppix recognizes my intel 82801 (or whatever the number is) sigmatel ac97 soundcard without any cheatcode, but when the desktop shows up, kmix can't find the mixer. so i try to run soundcardconfig and it tells me im not running the appropriate kernel - it says it cant find soundcard.o or something. any ideas? ive used alsa-intel8x0, alsa=intel8x0, emul10k, alsa, and nothing seems to work.
thank you in advance

I have the same problem on my IBM T42. The sound card is detected but there is no sound.

Run /usr/sbin/alsaconf as root and the sound card will work.

The best that I can tell, the sound card is not being configured correctly at boot time.

When using Knoppix 3.7, the sound card is configured correctly at boot time.

I had the same problem. It seems that the boot loading configuration script has some errors regarding sound configuration of certain chipsets. Mi soundcard is a generic Intel, using snd_intel8x0 and snd_ac97_codec.

I could solve it running in a root console alsaconf.

It first disables all the ALSA sound modules, then reinstall them again. Be sure you select YES when it asks you to modify /etc/modprobe.d/sound and /etc/modules.conf, if present. At least for me, it was the solution. After that, chose reload knoppix desktop and you should be done.

Its not a problem with the ALSA modules, since Kanotix uses the same kernel (2.6.11) in the last version (02-2005), but somehow they have avoided the sound loading problems.

I still haven't seen why Knoppix 3.8.1 cant configure the sound card for the intel8x0 while Knoppix 3.7 is able.

If the alsaconf script proves that the intel8x0 sourd card works, it should be able to configure it at boot time.

I've the same problem with a centrino i810 soundcard in a HP laptop.
If I start alsaconf, it locks up.
I can solve the problem starting knoppix with "knoppix noaudio" and then using alsaconf.
If I don't use "noaudio", the system isn't able to start X and I have to switch to another virtual console during boot and type "startx".

With "knoppix noaudio" it all works fine.
Hope it helps!

The Presario laptop worked fine under 3.7, but 3.8.1 has lots of problems with my hardware, including mouse, ethernet card, and sound.

On my Sony Vaio desktop, 3.8.1 works fine with the mouse and ethernet, but still no sound. Same thing, sound card found, but unable to find mixer.

Will try twr50's /usr/sbin/alsaconf as root and see what I get. It's frustrating to move from 3.7 to 3.8.1 and have so many things break.
