Hi, after a really rough year we've treated ourselves and got a Sony STRDN-1080 receiver to use with our late 2012 Mac Mini based home theatre system. However I haven't been able to get the Sony receiver to recognise the Mac Mini and to process 5:1 surround sound from it, even when using a HDMI 2 convertor. I've also connected our late 2013 MacBook Pro and that didn't work either. I wonder, do any of you might have any suggestions as to what the problem might be and how or if we can resolve it please? Interestingly connecting the Mac Mini directly to our OLED TV via HDMI allows the surround sound to work, but it should work when connected with the HDMI to the receiver.
