Good day, I have been trying to search and solve this issue for days not but to no avail.
My laptop is a Gigabyte Q1532n with onboard intel 3000 graphics and dedicated NVIDIA GeForce GT-520M graphic running windows 7 professional 64 bit. My laptop screen cracked so I decided to use it as a HTPC (home theatre pc) by connecting it to my LG tv via HDMI. My LG tv is connected to a Sony 6.2 surround sound amplifier via an optical cable.
so the connection goes like: HTPC(laptop)--LG TV--Sony Surround sound amplifier. Video output is perfectly fine.
The HDMI sound output is controlled by the intel 3000 hd audio driver and I have updated to the latest driver, however the HDMI is only outputting 2 channel sound even if i play video files with HD audio. I have attached my dxdiag report.
please note that I have connected my PS3 and my satellite hd receiver via the same configuration (device--LG TV--Sony Amplifier) and i get digital audio working fine so I'm assuming that my equipment setup is fine. I have also used a Mini PC with NVIDIA ION graphics on Windows 7 64 bit and windows 8.1 64 bit (NIVIDIA driver for HDMI sound) and got digital HD audio working fine via HDMI also cementing the idea that the equipment set up isnt a problem.
thank you in advance for your help, this problem is literally driving me crazy.
