And reverting the above fixes your problem, right? Then please give alsa-info.sh outputs on both working and non-working kernels (run with --no-upload option).

Yes, reverting that one hunk fixes my problem.

The alsa-info.sh outputs for the working and nonworking cases are attached.

Thanks. Through a quick glance at these information, the problem looks like that both newly appearing "Headphone" and "Speaker" volumes are set to zero. Usually alsactl invoked by udev will set appropriate values for new elements, but in your case, it didn't work by some reason.

Try to adjust them. (Note that you don't have to rebuild the kernel just for this test; pass model=auto option to snd-hda-intel module, then it'll switch to that mode.)

thanks,
