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 ?
