Patch (via Jakob Alvermark) to sys/dev/sound/pci/hda/hdaa.c for head at r339121
Patch was obtained form Jakob Avermark's post to -current, a copy of which is
at https://lists.freebsd.org/pipermail/freebsd-current/2018-October/071454.html
Note that I also added
# Test a possible "sound" fix
hint.hdaa.0.nid33.config="as=1 seq=15 device=Headphones"
to /boot/loader.conf.
The fix also applies to stable/11 (@r339120) (possibly with a bit of fuzz):
that is what I am running as I type this.
