The Official AC97/Via Onboard Sound Problem Thread Thingie

[KneeLess]

I tried the ALSA boot prompt cheat, and /etc/init.d/asla-config as root, but still...no sound. Some threads here said disable legacy in BIOS, but there was only USB Legacy, so I disabled that. Still no luck. Any other help?

(Also tried 'knoppix xmodule-fbdeva alsa'

What type of card do you have? If you have no on board sound you don't really need alsa.

Sorry, I thought it was evident that I have Intel AC '97 On board sound.

I apologize.

I apologize.

When you said there was no option to disable sound in the BIOS I assumed there was no on board sound there is usually an option in the BIOS to disable the sound in mine it is in the Intergrated Pheriphials so no apology is necessary. Getting back to the topic at hand have you confirmed that the card is recognized on boot by Knoppix, once booted use dmesg | grep AC97 this will show you all lines with AC97 in them from the boot messages. Also with my onboard sound (VIA VT82C686 AC97) I don't need alsa when I boot the CD and HD install it will work fine without it you may want to try without the alsa cheat code. Another thing you could check is lcpci -v and see if there are any IRQ conflicts with any other devices.

I have the Athlon 1800+, with onboard AC97 Sound, and I believe the via
chipset. My sound worked in the older versions of knoppix (KNOPPIX_V3.2-2003-05-20-EN.iso), then I upgraded to 2003-07-26 EN. Iso. and my sound didn't work anymore, will this fix it?

Thanks in advance,

Matt

If you mean booting with the alsa cheat code the only way to find out would be to try it.

Hi
I too am having problems getting my via ac'97 sound working. I am very new to linux. I went into shell and went to the etc/init.d directory. I can see alsa-autoconfig but when i type "alsa-autoconfig" i get "alsa-autoconfig: command not found" am i doing something wrong

Cheers

First are you root user when doing this? Second if you are root in the shell in the init.d directory try ./alsa-autoconfig.

To solve my problem with the AC 97 card on my system, i had to refer to a post on page 5 of this forum, It was wrote by Fabianx dated 28 Mar,
Log on as Root
open Konsole, or press ctrl+alt+f1
enter /etc/init.d/alsa-autoconfig
let it do its thing then reboot.
Hope it works for you too.

Some Suggestions

I have an AC 97 (AD1980) which was autodetected by the 'knoppix alsa' cheat. But the sound emerges on the 'PCM' and 'Surround' channels, and unless you use a dedicated ALSA mixer like alsamixer you may not be able to access the 'Surround' channel to unmute it and turn the volume up. Both these channels have to be on and turned up.

I believe knoppix turns up 'PCM' and 'Centre' by default. It took me a while to figure that out. I guess other AC 97's are different again on this.

One thing to try if you have no sound is to just run xmms on a sound file. If the LED's are jiggling you probably just have the wrong mixer settings.

I've upgraded my kernel to

2.4.21-acpi

But this has killed the sound in the process.

Here is the output when I run alsa-config:

root@Probot:/etc/init.d# ./alsa-autoconfig
Preparing modules for alsa...
Building card database..
Configuring via82xx...
Running update-modules...
Creating snddevices...
Setting default volumes...
aumix: error opening mixer


I've tried to apt-get alsa, aumix, and alsa-autoconfig, with no luck.

thanks

After use the ;

# /etc/init.d
# ./alsa-autoconfig

Sound works fine,but unfortunately I have to do this now everytime when I start up the computer again, what to do to let this been set permanently so I don`t have to set
this everytime?
