For 2D works perfectly well. Image on TV, via HDMI sound (DTS HD etc etc) on the receiver, all good. However, once a 3D signal is output from the PS3, I have the "opposite" of my original problem that I wanted to fix: While I get picture on the TV but no sound from the receiver. This obtains in this case, according to front display and no input signal.
Therefore, this splitter is not right for my case. For those who but "just" want to hang 2 displays at a source or the like it should work but.
