Yesterday, I received the WYWH Immersion set. I got it mainly for the bluray, specifically the quad mix - I already have the 5.1 mix on SACD. Popped the disc in, selected the quad mix and... front L/R channels only.
Oppo UDP-203 (2016)
Yamaha RX-A3050 AVR (2016)
I tried everything I could think of: Switching the Oppo from bitstream to PCM, swapping the HDMI cable from HDMI2 to HDMI1, different HDMI inputs on the A3050. I also tried the disc in a Sony, then a Panasonic bluray player - same result.
Conclusion: The Yamaha RX-A3050 does not recognise 4.0. This is disappointing as several Yamaha models are listed as 4.0 capable at the top of this thread.
Having read through this thread, it seems I have two options:
1. Buy a new AVR that can handle 4.0 properly.
2. Rip the bluray disc and add a silent centre channel.
I do not have a bluray drive in my laptop but an external drive will cost me a lot less than a new AVR. And all to do something my old Pioneer receiver could do without a problem. Presumably, AV manufacturers call this progress.
