No, it won’t act as a line out on the Sonos to a line in on the Mac. It works as a line in to the Sonos only, and isn’t a two way device. 

Because I saw a post on this forum that says it works in input record on an iPad so I was wondering if it could work on a Mac Studio. Sorry for my english 

Ah, I see. You’re not trying to take a Sonos signal, just any analog signal, and take it in to your Mac.

I think you could potentially connect an analog signal to the adapter and use it to feed a digital signal to your Mac. What it won’t do is take the digital output from your Mac, and change it into an analog signal to play elsewhere. 

This isn’t what it is designed for, but I don’t see why it wouldn’t provide a digital signal to the Mac. It would be up to the software on the Mac as to whether it would be able to recognize and process that signal.

Your forum account doesn’t suggest where you’re from, otherwise I’d use Apple’s translate to put my response in your language. 

Exactly ! Any analog signal to record in the Mac with the usb c :) 

If someone have the sonos line in adapter and a Mac, could you please try to do this please for me ? And tell me if when you plug the adapter, it appears in the audio menu setting of Mac OS like a record In Peripheral.

thank you !
