I did see the snd_hda_resume_ctls() code but noted it was resuming from
snd_kcontrol_new structures rather than snd_kcontrol instances. I'm
still not sure what the difference is here, are they supposed to
'mirror' each other?
Anyway, it turns out that snd_hda_resume_ctls() doesn't get executed.
stac92xx_resume() has this code:
for (i = 0; i < spec->num_mixers; i++)
On my system, spec->num_mixers is 0.
