No sound after upgrade to 2.6.21

mattd7591 · 07-11-2007, 04:49 PM

I just upgraded to the 2.6.21 kernel, as it just arrived in Debian Testing, and I have no sound.

Code:

 lsmod |grep snd

shows all of the modules are loaded. I ran alsaconf but amixer complains about no device

Code:

Loading driver...
Usage: /etc/init.d/alsa {unload|reload|force-unload|force-reload|suspend|resume}
Setting default volumes...
amixer: Mixer attach default error: No such device

KDE sopund sytem won't start for Alsa either
There is no /dev/dsp or /dev/snd/................

Output of alsa
[code]
matt-debian:init.d# ./alsa reload
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).

output of alsa-utils restart

Code:

matt-debian:init.d# ./alsa-utils restart
Shutting down ALSA...done (none loaded).
Setting up ALSA...done (none loaded).

Dmseg

Code:

matt-debian:init.d# dmesg |grep alsa
ALSA /usr/src/modules/alsa-driver/pci/emu10k1/../../alsa-kernel/pci/emu10k1/emu10k1x.c:949: Model 1003 Rev 00000000 Serial 10031102

I am stuck.
The soundcard is a Creative Sound Blaster Live on a Dell computer
whith the module snd-emu10k1x, which is loaded. Anyone have any Ideas or solutions?

But with slackware I have a similar problem after a kernel upgrade and recompiling alsa (if running as a modules) seems to fix it and recompiling the kernel if its built in might work.

i used module assistant to rebuild the modules

Did you recompile the alsa driver, library, lib-plugins, utilities, tools and if installed Firmware,pyalsa and oss compatability ?

re-installing alsa utilities and tools being alsa seems to fail amixer. not sure which package thats in.

You can't even get drivers for that card from Creative for Windows, it's a Dell OEM digital 5.1 card. But that's besides the point, I've been using the 2.6.21 kernel for well over two months now, I'm listening to my mp3s right now through Amarok on a KDE desktop, with a Sound blaster card, (not SB Live).
But!
A couple days ago I did some updates and Amarok was one of them, I couldn't play mp3s after the updates, apparently now you need a different package to play "unsupported" media. Had to install the libxine-ffmpeg package to get the tunes happening again. I tried your command 'dmesg | grep alsa' and got nothing but the prompt returning. Do you get sound when you play a music CD?. Have you installed another mixer and played with muting and un-muting things.
Try these commands:

Code:

$ amixer set Master 100% unmute
$ amixer set PCM 100% unmute

Ok. After uninstalling the module and rebuilding it with m-a, it worked.
After I restarted it didn't work
After playing around, after unloading and then reloading the modules it worked, but I had to do that each time I restarted.
When I did modprobe snd_emu10k1x snd_oss etc
(that isn't the code I use, just example), I saw it came exited with an error with aboutn emu10k1x
I did modprobe snd_emu10k1x seperately, then the rest and it worked.
The final solution was to put snd_emu10k1x in /etc/modules
Sound now works fine.
