i just switched my audio setup for an AVR and separate Dali Oberon speakers to a full Sonos system (arc, sub and one sl’s)
I have a 4K Samsung 65” TV (2020 model with eARC) and a Mac Mini M1 hooked to it as my media center.
When I had my AVR I got the Mac mini to play full Dolby surround via the AVR (HDMI all the way) (5.1)
Now that I have switched to the sons setups I no longer get the option of multi channel output to the Sonia arc via the TV only 2 channel stereo. The MIDI setup no longer displays the option of multichannel output to the arc via the TV
I have the TV set to atmos comparability “on” and digital audio output format “auto”
Mac mini connected to hdmi 1, and Sonia arc connected to hdmi 2 / eARC
if I play content via a usb drive on the TV I get full surround and atmos (tried a sample file via a usb thumb drive directly to the tv)
anyone have a clue how I can get my Mac mini back and working as my media center with Sonia and be able to use full atmos multi channel?
