Intel Audio Drivers "cannot probe codecs"

Nirbodha

I recently reinstalled Gentoo, and I'm back in the process of installing the necessities. The only thing that doesn't work now is the audio drivers. In the GNOME environment, the only audio output is the dummy one.

When grepping the dmesg for snd_hda_intel, I get the following.

You need both the snd_hda intel driver and the codecs.
Try

Thanks for the speedy response.

Forgive my naïveness, but how should I enable those in /usr/src/linux? I can search them up but I can't seem to change them.

Once again, your assistance is much appreciated.

The correct way is though "make menuconfig"

Thanks again for your response.

I successfully built the kernel and gave my system the good ol' reboot. However, the issue still persists.

Did you

I did do the following commands, to no avail. Also, my /proc/asound/card0 had nothing within it

HOWEVER, I didn't account for the fact that I'm a klutz. As mentioned prior, I had an EFI stub so I didn't have to hassle with GRUB (and to try to secure boot it). After making everything, I forgot to apply the vmlinuz file changes to the EFI stub. After remaking the EFI stub, it works.

Thank you very much for your help, alamahant. It was very much appreciated.

I had the same problem as this thread, and a search brought me here. I required a required a different solution, posting my solution in case anyone else can benefit.

My solution just involved changing my kernel option for CONFIG_SND_HDA_INTEL from built-in "Y" to a module "M". I had no specific intention of directly compiling this into the kernel, it just was that way. Obviously, there's some sort of race condition where the kernel's trying to install the codecs before something is ready. Changing this option to a module (which is loaded later) resolved my issues. I've no idea what the race is with nor really motivated much to figure it out - things are working now.

CONFIG_SND_HDA_INTEL and codecs need to be either all modules or all built in.

The codecs are loaded when CONFIG_SND_HDA_INTEL is initialised, so all the bits need to be there at the same time.

It's much like kernel code that needs firmware. All the bits have to be available at the same time.

Thanks for the info Neddy. Figured it was something like that. This will get filed in my head under "things I should remember" (but I probably won't).
