Hello.
First of all, sorry for bad English.
I have a problem: i have
* MSI A55M-p33 motherboard -> http://www.msi.com/product/mb/A55M-P33.html#hero-overview
* AMD athlon II X4 641 CPU;
* 2*4GB DDR3 1600
* Sapphire HD4730 GPU -> http://www.sapphiretech.com/presentation/product/product_index.aspx?psn=&pid=260&lid=1#
* Win 8.1 Enterprise embedded x64 OS.

And my problem is, that when i install everything, i can't get 7.1 sound to my receiver Denon avr 3310. I installed all drivers, amd hdmi audio drivers, then tried to disable realtek audio onboard controller for a reason that sound go direct from gpu and still nothing. Driver of GPU downloaded from amd website "AMD HD4xxx series".
After everything i updated bios to 2.0, and still nothing.
Enabled on board audio device, updated newest drivers from realtek, and still everywhere i see that max number of channels is only 2, while i understand it should show 7.1
How could i solve this problem?
