    Could you send me the output of 'sysctl dev.pcm' as well?

    Thanks,

    Jakob


Ok, try this:

sysctl dev.hdaa.0.nid33_config="as=2 seq=15"
sysctl dev.hdaa.0.reconfig=1

It should make it auto-switch when you plug in headphones.

If it works put this in /boot/loader.conf to make it default on boot:

hint.hdaa.0.nid33.config="as=2 seq=15"
