While I am waiting for my new MacBook Pro to arrive, I have started wondering how to connect everything together. My goal is to only have one cable to connect to the MacBook when I use it at home (which will be Thunderbolt 3 obviously). So I will probably get some sort of Tunderbolt-3 Dock with Displayport and Ethernet.
However, I am wondering how I should handle audio: I have a 5.1 surround system which provides both digital (optical toslink) and analog input (using three cinch cable for the different channels).
I know that I should be able to plug in a toslink cable into the 3.5 audio jack of the MBP (if Apple hasn't decided to remove that feature?). However, I would like to only have one cable as mentioned above, so I need to get the audio over USB-C / Thunderbolt 3 somehow.
Is this possible? What kinds of adapters would I need, so I can realize the following (basically I am looking for an adapter from TB3 or Displayport to Toslink (optical audio) or Digital Audio via Coax):
------------- -------------- ------------------
- - - DP== ==TL -
- MacBook - - Dock - ??? - AV-Receiver -
- - - - ??? - (5.1) -
- TB3=======TB3 TB3== ==DA -
------------ -------------- ------------------
TB3 = Thunderbolt 3 / USB-C
DP = Displayport (regular size)
TL = Optical Audio (Toslink)
DA = Digital Audio (Coax)
