HDMI audio works with 780g, but only 2CH, it will not passthrough DTS, DD, or AC-3.

Running HDMI for your video and an optical cable for audio will allow you to get full 1080p video with DTS,DD, or AC-3 audio to passthrough your receiver. Be sure when experimenting with the 780g chipset that you go into BIOS to switch between the two output formats SPDIF/HDMI.

Completely incorrect. Since Catalyst 9.3 the 780g/HD3200 will do DD/DTS 5.1 over HDMI.

Coolness.

That driver is only 10 days old so I don't feel bad about not knowing.

I will test it. Thanks.

My setup works:

LAPTOP
I use sony laptop VGN-FW390 with ATI Mobility Radeon™ HD 3470

REVCEIVER
Denon AVR-2807 - The laptop is connected to receiver using HDMI and the HDMI out from receiver is connected to plasma PANASONIC tv

NAS
H.264 video with AC3 5.1 streamed WIRELESSLY using DRAFT-N

The above setup works flawlessly and get full 5.1 dolby digital sound!
