I am trying to connect my HP Pavilion a1267c to my LG 50PZ950 TV via HDMI. The graphic card is a GSO 9600 and I don't think my Mobo supports SPDIF so I can't use audio over HDMI. I have a 3.5mm RCA splitter and a normal 3.5mm sound cable. I need a way where I can use HDMI for graphics and something else for audio. I just want some audio. I have also turned off the audio on the Nvidia driver. I do not know what to do now! I have also looked in the playback list. Nothing seems to work.
