Ok then, lets go back to basics then: Disable DTS interactive and send only PCM signals out [44.1 or 48KHz]. Does THAT work?
Sorry was away from my home and could not test it earlier.
I tried that and no result. I am not sure if this is a problem on my A/V Receiver where we need to get the audio input through optical instead of HDMI or is it a problem from my PC where audio is not coming out through optical cable. I do not know a way to determine whether audio indeed is coming out through my optical cable(S/PDIF), could you suggest me a way to test that please?
