Hi, I have just built a new computer and am having difficulties with HDMI audio. I gather from reading forums that this is a general problem with Windows 7 but thought I would look here for advice with my specific componants.
In windows control panel it is saying that my HDMI can only output two channel sound. I have tried with both the built in graphics chip and also with my graphics card but no joy. I have the latest Radeon drivers installed. The HDMI connected is connected to my Sony A/V amp and when my old computer (win vista) was connected it did not have any problems outputting 5.1/7.1 sound.
My system is as follows:
Gigabyte D77-D3H motherboard
Gigabyte Radeon 7850 OC
Intel i5 3570K (oc to 4.4ghz)
4GB Corsair Vengeance LP
Arctic i30 CPU cooler
Generic PSU til I buy a new one.
