I recently bought a i3-3225 with HD4000 GPU and a mb (GIGABYTE GA-B75M-D3H) with a B75 chipset on it.
When connecting to HDMI (only for audio) to my receiver I keep getting just a stereo signal (not the 5.1 I would like).
I tried looking in the audio setting, installed latest drivers etc. but nothing seems to help?
Is this a limitation of the GPU ? Chipset? HDMI? (Receiver accepts HDMI 1.4)
The OS I'm using is Win8 x64
Any help would be appreciated !
