I use a laptop with PC-BSD and couldn't get output over the headphone.
The built-in speakers of the laptop work fine and keep working even
when a headphone is plugged in (whereas on Windows they get muted). I
tried every slider and switch in KMix, but nothing enables sound over
the headphone.
This is my dmesg output:
