>Description:
Same dmesg as in PR pkg/46919. Highlights:

hdafg1 at hdaudio0: Intel G45 HDMI
hdafg1: HDMI00 8ch: Digital Out [Jack]

Devices clearly supports audio and i can hear some hissing on the device's
speaker when the cable is plugged in, so speaker for HDMI on device works.

Onboard audio: audio0 at hdafg0: full duplex, playback, capture, independent

Sounds works fine through that device.
