Thanks for joining the graphics community.
I understand you are trying to get audio through HDMI.
Intel offers generic video drivers containing HDMI codec, perhaps, that is exactly what you’re missing to connect your HDMI sound system.

Any solution on this question?
I have the same problem, its only show 2 channels.
I have the same setup: [PC]===HDMI=== [TV] ===OPTICAL===[RECEIVER] === [Speakers]
I have another desktop PC which i use in the same setup and its delivering 5.1 surround sound via the HDMI OUR on ATI Radeon Graphic Card
Where is the problem, in the bios, in the graphic drivers, audio???
My PC is Asus n750jk
Windows 8.1 64-bit
Intel Core i7-4700HQ
Intel HD Graphics 4600
NVIDIA GeForce 850M
Since you are using a switchable graphics computer, you may need to test if graphics drivers are causing this problem.
I recommend removing any Intel graphics and Nvidia driver from Windows Control Panel.
Download the latest drivers: File name: win64_153614.exe
Nvidia drivers here: Notebooks & Ultrabooks - N750JK - ASUS
Re install the drivers.
Additionally, please make sure you are using high quality HDMI 1.4 cables
Surround sound is available on Intel® HD Graphics 4600, see this link Quick Reference Guide for Intel® Core™ Processor Graphics | Intel® Developer Zone
It all depends on how the system has been integrated by your computer manufacturer.
Thank you Allan,
I know that surround sound is available on Intel HD 4600, that was what I told them, the ASUS support, but they replied whit this:
"The specification for the sound is as below and I can find no process in those specs that support 5.1
Built-in 4 Speakers And Digital Array Microphone
Bang & Olufsen ICEpower®
Asus N series external sub-woofer support
My questions are:
1. Can be this fixed by new bios?
2. How to find out, how the system has been integrated by computer manufacturer?
There are some issues that can be fixed through BIOS update; however, since this is an Asus motherboard, my recommendation still is to contact Asus for more information.
At this stage, only Asus would be familiar with the total configuration of your integrated system and the way all the features interact with each other.
