no sound :(

[aditsu]

I burned the latest knoppix (3 nov) and booted from cd; everything works fine except there's no sound
I'm a newbie (or at least beginner) so I don't really know what to do; I tried the kde control center but it doesn't see my sound card, and I can't find any way to add it
I did lspci -v as instructed, and the relevant part is:

00:0b.0 Multimedia audio controller: Platform Technologies, Inc. AGOGO sound chip (aka ESS Maestro 1) (rev 10)
Subsystem: Platform Technologies, Inc.: Unknown device ffff
Flags: bus master, medium devsel, latency 80, IRQ 9
I/O ports at e800 [size=256]

please help me out, and if you need me to give more information, just shout

thanks

here's some more information:
from lsmod:

maestro 28680 0
soundcore 3428 2 [maestro]

from dmesg:

you should tell someone about this.

I'm a newbie and pretty puzzled about quite a few things in Linux, but I know there is an install utility to help autodetect your soundcard and settings (if it is supported) called 'sndconfig' - type it at the root prompt.

Maybe that will help.

I had tried it, and it said it found a display setting and I shouldn't run sndconfig from X; I'll try again later in a text console (I'm in windoze now)

I've been quite busy, but now I got some time and I tried sndconfig again
here's what happened:
- it said it would probe some stuff, then it found a PCI sound card - AGOGO sound chip (aka ESS Maestro 1)
- then it said it would back up /etc/modules.conf and create a new file
- some messages appeared at the bottom of the screen:

depmod: can't open /lib/modules/extra/modules.dep for
ing
cp: cannot remove `/lib/modules/modprobe.conf.old': read-only file system

(yes, there was an "ing" on a line by itself, with no verb)
- sndconfig said everything was ok, and tried to play a sound sample, but I didn't hear anything, then it switched to manual configuration
- I selected the sound card (ESS Maestro), then it gave me an error: "there are already some sound config options in /etc/modules.conf - this could give unexpected results, please remove the appropriate entries from /etc/modutils/*"
and then I was back to the command prompt

I checked and /lib is a link to /KNOPPIX/lib, and /KNOPPIX appears to be mounted read-only
I also took a look at modules.conf and the modutils directory, but I had no idea what to do

so.. now what?

Hi Adrian,

I checked and /lib is a link to /KNOPPIX/lib, and /KNOPPIX appears to be mounted read-only
I also took a look at modules.conf and the modutils directory, but I had no idea what to do

so.. now what?

For a temporary test you can make /lib writable:

# become superuser
su

# copy /lib from readonly CD to read/write memory
cp -r /KNOPPIX/lib /ramdisk/libmem

# relink /lib to the copy
ln -s -fn /ramdisk/libmem /lib

This way you can check if 'sndconfig' can make your soundcard working.

Hi Adrian,

maybe the new version (2003-11-14) helps because it has a working ALSA again that was broken in your version. Try it with
knoppix alsa
at the bootprompt.

what? another download and another cd? hmm
so ALSA was broken in this version ?!! what about OSS?
and why is it necessary to boot with "knoppix alsa"?

thanks
Adrian

Hi Adrian,

OSS is used as default. If you want ALSA boot with "knoppix alsa" .

Ciao Martin
