Again, snd_hda headphones problem

[Zhihao Yuan]

Hi,

I posted this message on FreeBSD forum, but got no response. So I'm
seeking some help here.

I bought a laptop, HP Elitebook 8540w.

I have already set up the default_unit:

~> cat /dev/sndstat

And the sound comes from the internal speaker, and the internal record
works. But the sound does not work on the headphones.

I read many posts and the snd_hda(4), and I know I need to bind the
headphones and the internal speaker to the same as, and I need to do
the same on output. But I don't know which device is which, and I just
don't know how to deal with the seq. Please help me if you are pro on
this.
