Hey guys, I am having a hell of a time trying to get my system setup properly. I am using an Acer Revo RL70 running Win 7 Ultimate (x64). My relevant system specs are as follows:

Ram: 2GB DDR3 (will be updating to 4GB soon)
Graphics card: Radeon HD 6320
Processor: AMD 1.65 GHz E-Series Dual-Core E-450 
OS: Win7 Ultimate 64bit

I am trying to get 5.1 Surround audio through HDMI to my TV, however, when configuring my HDMI audio I can only see "Stereo" as an option. Furthermore, when I check out my "Max Number of Channels" I only see "2" when I know my graphics card supports the required 8 for Surround via HDMI. 

I have tried a plethora of drivers including the following:
-Default Windows Driver
-Catalyst 13.9: 13-9_win7_win8_64_dd_ccc_whql 
-Catalyst 11.4 (heard this fixes the issue with other cards): 11-4_vista64_win7_64_dd_ccc_ocl 
-RealTek ATI HDMI Audio R2.70
-RealTek High Definition Audio Codecs R2.71 

All of which only leave me with:
-Max Number of Channels: 2
-HDCP: Supported
-Bit Depths: 16-bit, 24-bit
-Encoded Formats: "No compressed formats found"

My entertainment setup is connected like this: PC connects to TV via HDMI; TV connects audio to 5.1 surround system via optical out. I know that 5.1 surroud should work fine like this because I have an Xbox 360, PS3, and Cable Box connected the same way that all sound much better, fuller, and more robust than the sound I get from my PC. I would just give up and hook an optical cable from my pc to my receiver but I only have 1 optical in and my TV is using that for everything.

As far as I can tell, this is a driver issue because I am not getting the proper specs on my HDMI Output screen. The only other possibility is that my receiver is not setup properly for this, I am using a Sony DAV-HDX275. I am not super up on my stereo equipment game, maybe somebody can help me, I found a link to the manual:®ion_id=1&tab=manuals#


Please help me, I am at my wits and I am starting to go nuts over this!
