Could you push a commit for the changes you made for ALC256 layout 21 to Acidanthera , so as to keep those changes with latest releases?

Latest commits may fix the problem with the audio from speakers working only after sleep.

Can someone please push a commit to Acidanthera ?

I don't know how to do it.

 

Here is the patched file

Thnaks in advance.

I'm sorry, don't have much time, but here's a kext where I added a new layout. Try it with layoutID 12.AppleALC.kext.zip

Thanks but not working for me.

 

If you have the time can you compile the new commits applealc 1.62 (that works with Monterey) with the changes you made for me on layout 21( see previous kext i uploaded).

Thnaks in advance for all your help.

No , with both 21 and 12 there is the problem with noise and cpu stack at max speed. That is because line in is back.

Sending you the kext you patched removing the line in.

Unfortunately I can't see the changes from this kext, it's just binaries. Try this.

I think I messed up something. You can try this kext, also run the new script with alc-verb from the attachment.

With this kext there is no sound at all from external speakers (and there is an unknown device in in input)

 

So, I switched back to old good kext and atteching logs from the script.

First is after rebooting , when there is no audio from ext speakers.

Second is after waking from sleep , when sound works.
