It is difficult to read this without original formatting, but below we
can see that you codec configured to provide separate audio devices for
speaker and headphones:

Usually in such cases codec configured to do automatic audio redirection
 on headphones plug-in, but for some reason not in your case.

So you may try to either playback via pcm1 device to headphones, or add
line:
hint.hdac.0.cad0.nid10.config="as=1 seq=15"
into /boot/loader.conf to configure automatic redirection. Also you may
want to read snd_hda man page, which describes it.
