CentOS - May 2009 - no snd-hda-codec.ko in CentOS 5.3 is that ok ?

Hello,

When I was running CentOS 5.2 (and other Liuux distribution) on an Asus
W2J laptop, I never get sound.

I upgraded to CentOS 5.3.
Now the sound card is recognized and plays the test sounds.
I checked channels with alsamixer, mix, kamix ....
I still have no sound using aplay alsa command or whatever else audio
display.

Trying to check my configuration I discovered that the snd-hda-codec.ko
is missing :

modprobe -l | grep hda

gives

/lib/modules/2.6.18-128.1.10.el5/kernel/drivers/hwmon/hdaps.ko
/lib/modules/2.6.18-128.1.10.el5/kernel/sound/pci/hda/snd-hda-intel.ko

Is that the reason why I have no sound ?

Regards,

Francois Colonna

did you try see the permission on:
ls -l /dev/dsp
ls -l /dev/audio
and ls -l /dev/snd/
?

alsamixer what say?

lsmod provides the correct module of your soundcard?

I do not understand why I get this owner instead of root ?
I changed colonna to root but at reboot colonna comes back !

It gives :
