Hello,
I use NomadBSD on a laptop HP ProBook 650 G2 (Conexant CX20724)
What works:
Internal (microphone + speakers)
External 3.5mm jack (Headphones)
What not works:
External 3.5mm jack (headphones with microphone, microphone not work)
solution
sudo vi /boot/device.hints
hint.hdaa.0.nid29.config=“as=1”
hint.hdaa.0.nid25.config=“as=2”
hint.hdaa.0.nid26.config=“as=3”
hint.hdaa.0.nid23.config=“as=4”
reboot and choose pcm0 with DSBMixer and now (headphones + microphone) work
for more information about sound on FreeBSD
