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.)

By adding that option to /etc/modprobe.d/99-local.conf, and removing my patch, I got new controls with the mixer. After fiddling with them a bit, I got working sound. The issue is fixed.

OK, thanks for a quick check!

BTW, are you using systemd or sysvinit? The culprit might be the missing call of "alsactl init" at the startup, and it depends on the start-up system, of course.
