I found a smart blue ray player with two HDMI outputs replaced the ps3 and was able to hook it up. I was thinking I could probably create the same effect on the ps3 if I had a splitter connected to the ps3, not sure though.
I'm trying to run sound and video from a ps3 to an Epson projector and lg so 9y sound bar via HDMI. I can get visual and audio out of the speakers on the projector but no audio from the sound bar.
