Have you tried using ALSA? Do a test from the cd by using the following at boot: "knoppix alsa"
Post back results.
P.S.
If this is on a hdinstall try running /etc/init.d/alsa-autoconfig as root
I recently installed Knoppix 3.2 on the hard disk of Toshiba Tecra 8000 laptop, replacing version 3.1. Now I am unable to play audio cd's or us xmms. On booting I get the info that "device /dev/dsp can't be opened (no such device) The sound server will continue using null device".
Under 3.1 the sound worked ok after installing modules: sound.o,soundcore.o, ad1848 and the following in /etc/modules.
alias sound-slot-0 ad1848
alias synth0 opl3
options sound dmabuf=1
options opl3 io=0x388
options ad1848 io=0x530 dma=1 irq=5 dma2=0
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>$1 || :
preinstall sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrxrc -S >/dev/null 2>$1 || :
Making athese changes under 3.2 is not effective. I have done extensive searches on Gloogle, Knoppix Forum and other sites without success.
Can anyone help me on this? Is there any link that can be added to /dev/dsp to fix the problem?

Make sure you are a member of the audio group (type groups in console window)Originally Posted by gfrick
and that you have read-write permission ls -la /dev/dsp to check. To add your self to group adduser < username > audio to make the device read-write for users chmod +urw /dev/dsp both these as root in a console.
[edit]
You have to log out and back in for the group addition to take effect.

It is a hdinstall.
There is no file /etc/init.d/alsa-autoconfig on my distribution.

gfrick is set as a member of audio and the permissions for /dev/dsp are 777.
ls -la /dev/dsp = crwxrwxrwx 1 root audio 14, 3 april 15 2001 /dev/dsp
The warning I am getting says that there is no such device as /dev/dsp.
Thanks for answering.

Hmm. ALSA was added only on the more recent releases of 3.2. But I forgot to ask if you have run sndconfig? Try running sndconfig as root.Originally Posted by gfrick

Hi;
Well sndconfig didnt help.
What irks me is that in the past I have installed RED HAT 7.1 & 7.3, MANDRAKE 9.0, aand NOPPIX 3.1 on this laptop and had no problem configuring the sound.
It all seems to come back to /dev/dsp. The warnings I get say this device cannot be opened as there is no such device.
I really don't know where to go from here.

Do you see any errors if you run "dmesg |less" ?
Perhaps you could post the output of "lspci"?
Apart from getting some information from theses sources and finding something to address, I can only suggest that you update to the latest release and see if using ALSA will help.
Hi
Output from dmesg that pertains to sound.
