I am having "No sound through HDMI problem" with my "En9500GT TOP/DI" graphic card. I have checked most of the "No Sound" threads a few hours, but all those solutions or scenarios are different with my situation.
Mother board: Gigabytes GA-E7AUM-DS2H
Graphic Card: En9500GT TOP/DI
CPU : Core 2 Duo E7400 Box (LGA775)
HDTV : Hitachi Wooo L37-X01
Os : Windows 7
The mother board has a integrated NVIDIA GeForce 9400 graphic card, and S/PDIF Pin.
I have done some test as the following:
1, No En9500GT installed in MB, Only integrated GeForce 9400. Both sound and video works Fine through HDMI to TV.
2, En9500GT installed in MB, with integrated GeForce 9400 enabled in bios.
2.1 Video OK, Sound OK through integrated GeForce 9400's HDMI output.
2.2 Video OK, no Sound through En9500GT's HDMI output.
3, En9500GT installed in MB, with integrated GeForce 9400 disabled in bios.
Video OK, no Sound through En9500GT's HDMI output.
I have tried to connect the S/PDIF line between MB and the Graphic card, it doesn't make any difference: no sound, no additional device detected. (According to the S/PDIF pin layout in MB, I think it is the only way to make it connectted, so should be correct)
Now, I need extra speakers connected while playing Game in HDTV, it is inconvenient and really made me feel stupid.
Hope someone can give me some hints on what I am not doing well now.
