Did this solution work for you? If so, can you provide more detail on how the audio from the receiver's HDMI connection was passed to the TV's Optical out? I have a Pioneer Elite VSX-53 with all my components connected via HDMI, and a single HDMI running from the receiver to my Sony XBR55HX939. My receiver will not pass the HDMI audio to its own optical out, so I cannot use the receiver to connect directly to the PX5, Pioneer has verified this, and it's in the manual as well. I was hoping to use the optical out on the TV to connect to my PX5 instead, but don't get any sound. Sony said that the TV will convert the HDMI audio signal to be used with the optical out on the TV, and I have verified this by connecting my PS3 and DVR to the TV's HDMI inputs, and was able to get sound to my PX5 using the optical out on the TV. However, the only time I don't get sound is when using the HDMI out from the receiver to the TV, and the TVs optical out to the PX5. Do I need to change any setting on the receiver or TV in order to have the HDMI signal passed to the optical out on the TV? I would like to be able to use 5.1 or 7.1 headphones with my PS3 for gaming and movies, DVR, and Apple TV. I would prefer not to connect the optical out from all of my components to the receiver in order to use the optical out on the receiver. Any ideas? As I have 2 HDMI outputs on the receiver, is there any headphones with an HDMI in? Thanks!
