I just got a new 2020 iMac (i9) and I have an old Logitech sound system I used to connect to my old Mac Pro via optical digital audio cable. The Logitech system only accepts digital audio input (optical or coaxial). I want to hook my iMac to it but have no idea how to go about it except via USB. I value the community here and would appreciate your suggestions. I know that the headphone jack no longer carries digital output (since 2017?) Suggestions?
 
You need a converter box that has a USB input and a digital-optical (toslink) output.

Numerous ones are "out there" and available.
 
You want a USB to Toslink (Optical or Coaxial) audio converter. Plenty of options on Amazon and they look to be very inexpensive.
 
I bought two different ones at Amazon trying to hook up an old Sony Sub to a new sound-bar. Very cheap

Thank you for the description. As I search for such an item on Amazon, I am not seeing anything with a USB input. Do you have a link to something that worked for you?
