Every time I start KDE3.1 this error occours :
"Error while initializing the sound driver:
device /dev/dsp can't be opened (No such device)"

/dev/dsp and /dev/mixer have both read and write permissions
for user, group and others.

The command /sbin/lspci gives this output:

The modprobe soundcore return no output but the command modprobe i810_audio return thi error:

Any suggestions ?????
Thanks.

Perhaps you need to install kernel-sources?

Basically KDE is not finding your sound driver. It is not loaded

You have several ways to go about getting sound

Use the kernel sound drivers(recompile your kernel), use alsa which has good instructions for the AC97 drivers on their website or get a cheap sound card and uncomment the appropriate driver in /etc/rc.d/rc.modules

The kernel sound drivers are easiest but do not deliver the features and quality of the alsa drivers.

Alsa compiles sound modules which are then loaded by scripts in modules.conf in linux 2.4.xx. Alsa will become the standard sound drivers in linux 2.6.xx

Also look at this previous post, seems alsa is the best way to go

http://www.linuxquestions.org/questi...threadid=55624

Where may I find the ALSA drivers ???

I tryed with www.alsa-project.org but the browser say the URL is not correct .....

Try again. Their server must have been down as it is working for me.

Here is the Alsa howto for your chipset.

Alsa for Via 8233 AC97

I would follow these instructions rather than the ones in the previous thread as they compile drivers for all alsa supported cards and you only need the one driver, ie when you compile the alsa-driver use ./configure --with card=via82xx --with-sequencer=yes

Thanks a lot !!!!!!

I installed the ALSA drivers and now the "could not open /dev/dsp" error is disappeared.

But I'm not able to unmute the mixer (therefore I cant' ear no sound).

I tryed with alsamixer in thr alsa-utils directory (as told by the how-to) but this is the error:

alsamixer: function snd_ctl_open failed for default: No such file or directory

I tryed also with

amixer set Master 22 unmute
amixer set PCM 22 unmute
amixer set CD 22 unmute

but comes this error:

amixer: Mixer attach default error: No such file or directory

What can I do ??? Thank.

I tried for a long time to get my onboard sound working (its the same VIA chip you have I think), but it just wasn't happening. The 2.4.21 kernel however specifically has support for this chip and apparently it works. I haven't had chance to test it yet (I cheated and stuck a PCI sound card in! :-/) but I may get chance to have a look this evening.

munkeh

By default the alsa sound system sets all mixer levels at zero. The mixer depends on your desktop. KDE uses Kmix which is under Multimedia.

I tryed with Kmix but the only things i see are:

"Save Current Volume" "Load Volume" and "Load Volumes on Login"

What I have to Do ?????

Never Mind. I was looking in the wrong place .

Now the sound works fine.

Tanks to all.

ok, this is my /sbin/lspci, and I think it looks really weird, what do you guys think? Btw, my sound doesn't work either, but I have only had slack a while now so I'm not worried.

Thanks for your help,

It looks OK to me.

I don't see a sound card listed.

IIRC, the Intel Corp. 440BX/ZX/DX boards don't have on-board audio, so you will have to install one for sound.

I do not see a sound card in your pci listing. The 440BX chipset is older and chances are you mother board does not have an onboard sound chip. I would double check the back of the computer for 3 tiny RCA jacks on an isa or pci card. Unless you have an isa card you will likely have to purchase one. Soundblaster 16 and anything based on the ensonic es1370 or es1371 chip are easiest to setup

in windows I have sound though

Thanks,
Cam
