i currently have a Yamaha 863SE and am planning to get a Samsung 4K TV, Samsung UHD Blu Ray and shortly Sky Q. My current pre-4K stiff is all connected via HDMI to the Yamaha and switched using that. I am currently undecided whether to get a new AVR (such as a Denon 2300) because I don't really get the benefit of surround sound with kids in bed limiting volume and bass, so am considering a Q Acoustics M4 which would be connected with an optical from the TV. So here is my question. Can I connect the 4K Blu Ray and Sky Q to the TV then push audio from the TV out using a digital cable to the Yamaha? Then do the video switching using the TV menu and use a single audio channel for all audio out? This would give me more thinking time about whether to get a new AVR or the Q Acoustics. Thanks for advice. Haven't thought about this stuff for years so not up to date with all tech stuff on 4K.
