Been Googling all over but haven't found a solution, gone through my User Manual with no luck, so I'm at my wits end!
I have Sony Bravia KDL-32V4000 connected to my PC (Windows XP) using DVI-HDMI adapter for video going into HDMI 3 on the Bravia, and running 3.5mm - 3.5mm audio from my PC to Audio Input next to HDMI 3. I know the Line out works on the PC because I can hear it if I use a headphone.
Problem is if I select HDMI 3 on the TV as the input source the sound comes on for about 1/2 second then disappears leaving only the video!! So it is getting the audio but not continuing to play the audio. It seems as if the TV doesn't know that the Audio connection should be the input, but I can't see any place in the Bravia setup to specify that.
