Subject: azalia patch: 1. crashes X11, 2. monitor loses signal entirely?

Hi.
I've compiled everything on 7.5 release and applied only 1 patch:
https://marc.info/?l=openbsd-tech&m=171588776531605&w=2

I've noticed that while watching some videos, if I frequently spam sndioctl
commands (aka regulate volume level):
sndioctl output.level=+0.025
or
sndioctl output.level=-0.025

then SOMETIMES X11 or something crashes...
There are 2 types of crashes related to this bug.
case a:
  xenodm or X11 crash and I can safely skiddadle to the 1st tty and restart
  xenodm, everything works fine after that

case b:
  the entire display just stops getting signal, the computer is still running,
  is this some sort of harder crash?

Right before both cases, the screen freezes for a few seconds.
So basically yeah, adjusting audio volume can crash your display and stuff.

Some additional info:
I also (un)fullscreened mpv while executing shortcuts for mentioned sndioctl
commands, so this might have contributed to it?
I've ran OpenBSD for years on a few computers, and I've never had this
happen to me, especially not a few times within like 2 hours.

Tell me if you really need some more information, think of this as sendbug with
the -D option for privacy, but if it's REALLY needed, I just might censor the
files..

By the way, I have apmd with -L option, as well as obsdfreqd(1) runnin'.
