Hello! I recently installed FreeBSD 13.1 on an HP ProBook 450 G2 laptop.
Installed the latest version of the drm-kmod package. And I ran into a problem:
the sound through hdmi sounds slowed down by about half (the video also slows
down during playback). This behavior is independent of the sound source (even
cat /dev/urandom > /dev/dsp0.0 will be heard slowly). I studied the problem and
realized that it is rare, but sometimes it appears. In the Linux environment,
it skipped around 2016 and did not pop up after.
