No audio on HDMI output

I can output video though HDMI just fine, and audio through the front and rear jacks just fine, but when I switch hw.snd.default_unit to pcm0 (HDMI), cat /dev/random > /dev/dsp doesn't work.

cat /dev/sndstat: http://pastebin.com/KCdxB4Jh

cat dmesg | grep hda:

I took the pindumps with the HDMI plugged in, but not the analog jacks.

It didn't work on FreeBSD-10.0-RELEASE, but since I wanted newcons I'm on SVN head.

+1: It didn't work with FreeBSD 10.0-RELEASE (but worked earlier with FreeBSD 10-Beta3 with kde4, but I replaced the entire operating system and reinstalled gnome2)
