I can use beep -d /dev/dsp0 or /dev/dsp1 and hear a sound at the rear or
fron audio jacks.
If I send the beep to /dev/dsp2, I hear nothing.
I believe there is missing magic in i915kms.ko that routes audio from
the video driver to the audio driver. Or perhaps I need a hint in
/boot/loader.conf or /boot/device.hints?
I am using the snd_hda.ko driver in FreeBSD-14p6.
I also have linuxkpi_hdmi.ko in kldstat.
I can't find man pages describing these components. There are man pages
for drm and drm-kms, but they don't contain magic, like loader settings
or device hints.
I haven't been able to get sound from FreeBSD on this system for years.
Linux Mint, KDE Neon, and Ubuntu 24.04 DO deliver sound to the hdmi/dp
port.
