Hello,

I have build the vanilla kernel 3.2 for my system and the audio stopped working. I am using the module snd_hda_intel and everything worked great with 3.1.6. I have looked in the messages -> no errors. In proc is a sound device for alsa and the same config works with 3.1.6. Has somebody an idea what I am doing wrong? The pcspkr module is not loaded. Has something changed in 3.2 that needs to be configured?

uname -a : Linux hawk 3.2.0 #2 SMP PREEMPT Sat Jan 7 00:29:18 CET 2012 x86_64 Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz GenuineIntel GNU/Linux

proc/asound/cards : 0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xd1700000 irq 48

Has somebody an idea?

Sven

Hello,

I have tried a new kernel config. But still no success. Do you know a kernel forum where I could post the problem?

# alsaconf
# /etc/init/alsasound restart


fixed it for me.

Well. I was wrong. Sound only works via headphone output, not the built-in mono speaker.

Howdy, I've been battling this to for three days... I also thought maybe a kernel config. My config work great with Gnome 3.2.1 and kernel-3.1.6. I did a fresh install with KDE and genkernel and still no sound. It was solved by installing pulse-audio and disabling my bios' sound device. Reboot, and the right card was detected and work....

Hi I have the same problem. It is possible to fix it without instaling pulseaudio?

We have to wait for an upstream fix, pulseaudio is not going to land on my systems.

Not that I am aware of. A fix maybe in the works. But I found no evidence of any tho. I had tried a millions things as to fix it on my system. As to, I didn't want pulse on my system. But, I gotta say. I'm impress with it.
It just works, and the wiki for it is wrote very well. Russ

Has anyone tried building the audio driver into the kernel instead of building a module? I've no reason to think this might help, but just wonder.

I use almost entirely stable Gentoo, so kernel 3.1.6. I changed to using built-in audio drivers a few kernels ago to get round a problem where sound cards kept changing device numbers, and have had no problems with it since.
