Sound only working for root

[Edwin]

Hi,

I have installed Knoppix on my Toshiba laptop. This has an onboard soundchip which is recognised; this is some output from 'lspci -v':

00:1f.5 Multimedia audio controller: Intel Corp. 82801BA/BAM AC'97 Audio (rev 03)
Subsystem: Toshiba America Info Systems: Unknown device 0001
Flags: bus master, medium devsel, latency 0, IRQ 11
I/O ports at ce00 [size=256]
I/O ports at cdc0 [size=64]

The strange thing is that the sound only works when I login as root. When logged in on my user-account the silence is deafening

Does anyone have any idea where to start looking?

Oh, when I ran 'sndconfig' the chip was detected also. But then I got a message like 'error writing config file'. Sadly it did not say which error or which file. I'm pretty sure I ran this only from my user-account. Could that have anything to do with it?

TIA

Try adding yourself to the audio group.

vim /etc/group

Try adding yourself to the audio group.

vim /etc/group

Thanks for the suggestion.
I tried it, but allas, it does not work. In fact now I am a member of the audio group and root is not (and has never been ). But root has sound and I still have silence.

As root in a console window /etc/init.d/alsa-autoconfig to create the devices for the ALSA sound system. When you re-boot the sound levels will be lost edit the file /etc/init.d/bootmisc.sh and add the line aumix -w 75 -v 75 to have the mixer levels automatically set this also as root. You may also want to check this thread to get the most out of the sound system.

Well, my install did not have alsa, so I installed it but then there was no alsa-autoconfig. I wrestled with this for a few hours and then I saw the light:

Start -> Control Center -> Sound and Multimedia. Enabled 'Start aRts soundserver at startup' and 'Run soundserver with realtime priority'. That did the trick; problem is solved.

Thanks to all who responded,
