HDMI audio?

Hello,

Does OpenBSD support HDMI audio? I bought a new monitor, which has
integrated speakers. It's an LG 32UN650. Display is working really well,
but I can't get sound to work.

sndioctl output:

input.level=0.486
input.mute=0
output.level=0.494
output.mute=0
server.device=0(azalia0)

dmesg:
