Apologies if this is the wrong place to put this but I've recently built a custom gaming HTPC and everything's working well apart from I can't get 5.1 over HDMI from my AMD 7770. If I right-click the volume icon and attempt to configure the listed device it only ever gives me the option of 2 channel stereo.
In terms of setup, the 7770 goes into a Sony STR DH800 receiver via hdmi and i'm running the 64-bit Win8 preview. I'm fairly certain the issue isn't with the receiver as I used it with a laptop previously to get 5.1 via hdmi with no issues.
I'm wondering if it may be a driver issue. I've tried Catalyst 12.6 + 12.7 beta to no avail but have noticed that rather than being listed as an AMD High Definition HDMI device, it appears as a generic High Definition HDMI device, i.e. no mention of AMD and when probing further the drivers seem to be Microsoft, suggesting that maybe the AMD audio component of the catalyst suite isn't installing. Perhaps this relates to the issue?
Any help is much appreciated.
