[ HDMI no sound to LG HDTV 32LD350 ]
Problem: No sound between PC and LG 32LD350 Full HD via HDMI cable
Gigabyte GA-965P-S3 rev.3.4 motherboard
NVidia GeForce 9800 GT with HDMI port
LG 32LD350 Full HD 1080
When you connect HDMI cable there is video but no sound to LG TV.
Control Panel -> Sound -> Playback shows two devices.
Speakers (default device)
Realtek Digital Output
When you right click on Digi Output device -> test is seems like functional but still no sound.
You need to connect 2 pin cable from you sound card SPDIF-Out to your video card SPDIF-In.
In my case RT sound card is on motherboard but there are no SPDIF-out pins. I got only Cinch(RCA) output
on the motherboard itself. Solution is to modify 2 pins cable that comes with video card and plug one side
on the video card (in this case GeForce 9800GT) in SPDIF-In and Cinch(RCA) one at back of your PC in RCA
SPDIF-Out motherboard port.
