!!! This caused a regression in the i-g-t drv_module_reload_basic test.
Reproducible easily on HSW (i5-4460) with: #rmmod snd_hda_intel
I couldn't reproduce this on my HSW machine. Does it happen always without without the monitor plugged?
Reproducible with or without the monitor plugged in, just tested. Play a bit with rmmod/modprobe on snd_ha_intel and you'll get it. It's not always first time, but easy to catch.
Hmm, it still doesn't happen here... Does the bug disappear when you revert the commit?
The commit couldn't be reverted as is, there were dependencies to other commits. But reverting the entire sound merge fixed the problem. That was just to save our CI.

commit 25e4abb33df3aafa7d1efba8f82f9178268efab1 Author: Libin Yang libin.yang@linux.intel.com Date: Tue Jan 12 11:13:27 2016 +0800
ALSA: hda - hdmi jack created based on pcm Jack is created based on pcm. Apply the acomp jack rule to dyn_pcm_assign. For dyn_pcm_assign: Driver does not use hda_jack. It operates snd_jack directly. snd_jack pointer will be stored in spec->pcm.jack instead of the current spec->acomp_jack. When pcm is assigned to pin, jack will be assigned to pin automatically. For !dyn_pcm_assign: Driver continues using hda_jack for less impact on the old cases. Pcm is statically assigned to pin. So is jack. spec->pcm.jack saves the snd_jack pointer created in hda_jack.
