I am trying to play a BluRay disk on my Y710 and cannot get the audio to work. I'm using a standard Y cable converting 2.5mm headphone jack into 2 male RCA plugs. In the Realtek High Def Audio control, I specify Realtek Digital Output and then connect my cable into the headphone out connection and then the other sides of my cable to my digital coax inputs to my receiver. No matter the configuration I do not get digital audio out of my Y710... I've cross tested this using my desktop's SPDIF out and it worked fine going into my receiver.
Just wondering if I am missing something here and if anyone has been able to playback a bluray disk using HDMI only for video onto an external display while using SPDIF for audio into a receiver?
