This workaround is needed to have working headphones redirection in the Mini Jack port.

These lines in /boot/device.hints file followed by reboot(8) solves the problem:

# SOUND ON HEADPHONES
hint.hdaa.0.nid31.config="as=1"
hint.hdaa.0.nid25.config="as=1 seq=15 device=Headphones mute=0 misc=0"
hint.hdaa.0.nid28.config="as=1 seq=15 device=Headphones mute=0 misc=0"
