The Big 5.1 Blunder

[iamtpb]

I have a Dell Studio XPS 16 with ATI Radeon 4670 and thankfully has an HDMI output , It used to play properly few days ago and suddenly , it stopped playing audio after i installed Win 8 Pro , but after installing Realtek drivers for ATI HDMI Output it was working again but the output plays only the Center Speaker , none other speaker works not even the sub .

Connections-
LAPTOP---HDMI---> Sony TV ---Optical/HDMI--->Sony Home Theater & BD System

Have you tried installing the newest amd driver for your 4670? The driver package for it should have an hdmi audio driver included.
