we've got Chromecast and a Panasonic 42" LED TV about 6 yrs oldI've used our 2013 MacBook to watch youtube clips and other websites on the TV no problems - the sound comes through the TV speakersA couple of months ago we bought a new Marantz receiver and set it all up with our wharfdale speakers - it works fine and even when we turn the Panasonic TV on it automatically turn the Marantz on which is greatbut last weekend I was watching the All Blacks game live on the MacBook, then cast it to the TV on chromecast and it was great.... except there was no soundUnder sound preferences on the MacBook there was 'Marantz receiver' so I selected that but no sound came out of either the home theatre speakers or the TV speakerI turned the Marantz off but still couldn't get any sound out of the TV... the only sound I could get was if I plugged headphones into the MacBook. does anyone have any ideas how to get the sound working through either the Marantz receiver or the TV speakers?
