I have a PNY GeForce GT 630 Graphics card - low profile - 1 GB - DDR3 SDRAM Graphics card I just purchased and wanted to use the HDMI output to my Sony Wega 55 inch TV (KDF-55wf665) I plugged in the HDMI and picture is amazing! NO SOUND! I messed with settings in Device Manage/NVidia Control Panel nothing.... SO, I bought a 3.5mm to RCA cable and plugged that in... Still nothing! I have no idea what else it is! I'm sure it's something small, please help!
