Multichannel - Not detecting by Mac
I am having macbook air m1. I have connected my mac through hdmi-hdmi audio converter (HDMI input , TOSLINK output) to the Sony HT-S20R sound bar which has 5 speakers and a sub woofer. In Audio MIDI setup, instead of 6 channels, it only shows 2 channels detected. Will this be fixed in OS update or any mistake done in the connection? Please anyone suggest. Thanks.
