Just tried this on my Sony LED TV.texasbrit said:There have been virtually NO TVs that pass 5.1 on the optical out, when the input is via HDMI. A couple of Toshiba models did this, but very few others. Are you sure you are not confusing 5.1 with the "synthetic" Dolby surround that your A/V receiver creates from the PCM that comes from the TV?
HR24 feeds Sony TV with HDMI. Also has an optical line to Sony Receiver (older model, no HDMI inputs).
Sony TV output feeds Sony Receiver via Optical only.
I can switch inputs on the Sony Receiver between the HR24 optical and Sony TV optical out and get 5.1 either way.
If this is "synthetic", how would I know?
