Hi

Question regarding the backend and the sound card installation :

I have an installation problem with my soundboard, ok that's a very old one, an SB16 compatible.

How can I force alsa to detect it and to use it ?

When the sound (/etc/init.d/Sound) is starting, I got that error msg : aumix: error opening mixer

The backend is giving this error :

Cannot open DSP '/dev/dsp', dying.
open: No such device
Could not detect audio blocksize

Thanks for you help

You should be able to do '/etc/init.d/alsa-autoconfig' to set up your '/etc/modutils/alsa-0.9-knoppix' settings file.

If I'm not mistaken, I had to edit this script as it was looking for 'lspci' at '/sbin/lspci' instead of '/bin/lspci' . Just make that change and all should be well.

Good luck

I also just put in an old sound card (sound blaster AWE 32 ISA). I ran alsa-autoconfig but I still don't have any sound. When I try to watch a recording I get a blank screen. After I kill the process, I get a bunch of

Error opening audio device (/dev/dsp):
/dev/dsp: No such device
player: Can't open audio device: /dev/dsp

My files were encoded using a PVR250 - which I am able to verify on another machine (win xp).

Also, aumix won't start for me either.

Without turning this into an alsa support forum, can you post the contents of '/etc/modutils/alsa-0.9-knoppix' and 'lsmod' ?

I don't have anything at /etc/modutils/alsa-0.9-knoppix .


Here is my lspci output:

Well that's a problem. That's the file that specifies what module(s) will be used for sound.
It looks like autodetect is not working, so you will probably want to manually configure it.

If you're using a SB16 PCI sound card, check out:

http://www.alsa-project.org/alsa-doc/do ... le=ens1371

from that page, you should make your /etc/modutils/alsa-0.9-knoppix read something like:

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-ens1371
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

Then you'll have to do a 'update-modules' followed by a 'modprobe snd-card-0' . Then when you do a 'lsmod' (not 'lspci') you should see the 'snd-ens1371' module loaded and listed under 'sound' . Then you'll want to fire up 'alsamixer' and adjust your volume, capture source, etc ...

I'm not an ALSA expert, but I have had a fair amout of practice with configuring it when I added my second sound card.

I have an ISA card the Sound Blaster AWE 32. Does this still apply?

My guess is that you will have to go to google for that one unless someone here has a better memory than me. I held on to my awe32 long past it's time, but I still gave it up over two years ago. It worked fine, but I can't remember what all was involved in getting it working at the moment.

I found an SB Live on my windows box which I could probably swap in. I imagine that this will be much easier to setup. Tier 1?

yes the sblive will be autodetected and configured when you run the sound script.

You'll need run the alsa-autoconfig script followed by update-modules...

Thanks.

That appeared to do the trick. I have sound (and video) now but the sound is really faint (barely audible with the sound cranked up). I tried adjusting the channel volume in alsamixer but I can't save the levels. From what I understand, this is normally done with ...

"alsactrl store"

but that doesn't work.


aumix is another option - but it doesn't show all the channels on the live card.

I have a Creative SB 128, it is detected as a ens1371 card in alsa-0.9-knoppix. I can adjust all the mixer slides to no avail. I have no audio in: Tux Racer, an imported DVD and an imported CD. I followed the posts in this thread and in the alsa-project site and I am now suffiently confused and still without sound. Any thoughts, or commands I can try to give more valuble info?

I've heard lots of people having problems with the soundblaster pci128's I would go with another card if possible.

I had issue a while back with an onboard SB-16 compatible sound card.
Finally got it working (after trying everything I could find on this and other boards) by using RedHat's sndconfig.
There are debs available. I don't remember where I found them though.
