Alsa info

Ever since kernel 6.12 dropped for Fedora, my laptop only shows a dummy output. This is probably due to the kernel removing legacy sound drivers and replacing them with avs, which doesn’t seem work for the kaby lake architecture present in this model. (phoronix).

I am unsure whether or not I am filing this bug in the right place. Since I am able to get the microphone to work by copying a file: cp /usr/share/alsa/ucm2/conf.d/avs_dmic/Acer-Lars-1.0.conf /usr/share/alsa/ucm2/conf.d/avs_dmic/avs_dmic.conf I am guessing this is a case of a missing ucm file for this particular hardware. If this is incorrect, I would appreciate if someone could point me in the right direction and tell me if this is rather a bug with alsa-firmware or the kernel itself.

There is work in progress: #499 .

@amadeuszslawinski-intel

Intel SST drivers were removed too early IMHO.

Thank you for the update. I'm having a bit of a hard time following the progress on this issue. As far as I can tell, this requires both patches to the kernel and to alsa-ucm. Have the kernel patches been applied to the mainline kernel by now? Which patch would I need to apply to alsa-ucm in oder to get sound working on my laptop again?

Hallo PAVETHEM I had the same problem into the same PC as you: good news the problem is solved with a patch in Kernel 6.15.2-1. Please look here: https://bugzilla.opensuse.org/show_bug.cgi?id=1243826 and here: https://forums.opensuse.org/t/internal-microphone-does-not-work/185129

Thank you for the update! Unfortunately it doesn't seem to have been backported for the fedora kernels yet. However, the 6.16 release client kernels work.
