Your default device is currently the HDMI output on your graphics
card. You probably want to play with sysctl snd.default_unit=1 (or 2)
to set it to one of the analog outputs. One should be the front audio,
the other one should be the back.

Once you've got it sorted out, add to /etc/sysctl.conf to persist it.

Cheers
