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,

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.

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.

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

Hi,

I tried the proposed BIOS update but it doesn't work.

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 tried alsamixer that effectively change some things but didn't look for lsmod.

I will try and see.

Bye,

Miguipda ;-)

Did you get any sound?
Good luck.

Hi,

sorry but I was so busy with my examens.

No sound yet.

Thanks,

Have a nice day... bouhouhou ... hihi ...

Did you try alsamixer after the bios update?
Good luck.

Yes of course.

Bouhouhou ... hihi ...

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.
