I am using a optical cable from the mini-jack on the mac mini to the optical in (CD) on my Onkyo receiver. I cannot get any sound even after choosing the External Headphones (Headphone port) in the sound out on the Mac. Any ideas as to why not?
What year model is your Mac Mini?
Identify your Mac mini model - Apple Support
None latest Mac's including the 2018 and 2020 M1 Mac mini's with a single 3.5mm port support Optical Digital output.
To get Optical Digital from the newer Mac's, you will need to use a USB to Optical Digital adapter or DAC.
Yes.
Although I would probably opt for the USB-C version.
