I can use beep -d /dev/dsp0 or /dev/dsp1 and hear a sound at the
rear or front audio jacks.
<div class="moz-forward-container">
<p>If I send the beep to /dev/dsp2, I hear nothing.</p>
<p>I believe there is missing magic in <span
style="font-family:monospace">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?</span></p>
<p><span style="font-family:monospace">I am using the snd_hda.ko
driver in FreeBSD-14.1<br>
</span></p>
<p><span style="font-family:monospace">I also have
linuxkpi_hdmi.ko in kldstat.</span></p>
<p><span style="font-family:monospace">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.</span></p>
<p><span style="font-family:monospace">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.<br>
