Hmm. Almost works. If is set hw.snd.default_unit=1, the speakers are
off whether the headphones are plugged in an when they are, I only get
sound from the right channel and the volume control seems to be
non-operative. Even mute does nothing. This is on 9-STABLE which has
the new sound stuff. I see the following as "available":

So I have headphones on nid25 and 28, but I think 25 is the one that
is really there and 28 is the one when the unit is in a docking
station. But that does not really tell me how to make it work. Still,
I have only scanned the man page. It's after bed time here and I will
actually read it tomorrow.

I want it to behave like it does on Windows where I get sound on both
without touching anything and the speakers cut out when headphones are
plugged in.

Thanks!
