Unhappy No sound with cs46xx on my ibm thinkpad a21p under dapper drake


Hi,

I have an IBM Thinkpad A21p where the sound card is a CS46xx.
I tried all I known but I can't have sound.
Can somebody help me ??

Sincerely thanks,

Miguipda ;-)

$ lspci | grep audio
0000:00:05.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 01)


$ lsmod | grep snd*

snd_page_alloc 10632 2 snd_cs46xx,snd_pcm


No sound with this test :
$ speaker-test

speaker-test 0.0.8

Le périphérique de lecture est plughw:0,0
Les paramètres du flux sont 48000Hz, S16_LE, 1 canaux
Utilisation de 16 octaves de bruit rose
Taux fixé à 48000Hz (demandé 48000Hz)
Taille du tampon entre 32 et 32768
Taille de la periode entre 16 et 1024
Périodes = 4
Durée du tampon 2525
Définition de la taille du tampon = 32768
Définition de la durée de la période = 8192
La durée de la période à été définie= 1024
La taille du tampon à été définie = 32768
0 - Avant Gauche
Temps par période = 2,312040
0 - Avant Gauche
Temps par période = 2,986373

I set all on with :
$ alsamixer


I checked if something undesired :
$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

lp
psmouse


And checked that the user is well with the under group audio, it is.

Hi, I found this

"6. Sound

The A21p comes with a Crystal SoundFusion PCI soundcard. Redhat 7.0 automatically configures it, but it did not produce sounds. Disabling "PCI Bus Power Mgmt" in BIOS menu did the trick. Push [F1] at startup, and disable <Config> - <Power> - <PCI Bus Power Management> (last entry, scroll down!)."

here.

http://www.neurophys.wisc.edu/~cai/linux/a21p/

It appears to be an older document, but it's worth a shot.
Good luck.

If the bios fix didn't work I'd try some different settings in alsamixer. Toggle a few things on and off, etc. Did you run through lsmod, and alsamixer after changing the bios?
Good luck.

I'm fresh out of ideas, all the modules are loaded, are you getting any errors? Let's have a look at dmesg please?
Good luck.
