    I’m sure you’ve already checked, but…

    Have you checked the routings in the Audio/MIDI set-up menu?

    Are you sure that it is an optical problem and not an audio problem (audio routing is correct, speakers are on and properly connected, etc.)?

    Are you using the original, MKII or MKIII?

    What DAW are you using?

    Nor sure about MOTU and the 828, but some units are finicky if you don’t use both the optical in and out.

    Hi Ross. My first basic lenscap question:

    Have you tried using a FW400 to FW800 cable? Plugging the 400 end into the 828 and the 800 end into one of the 800 ports on the Mac Pro?

    I will try to make this simple explanation:

    MacPro has an optical audio IN/OUT

    get an TOSLINK optical cable like this https://bit.ly/2tSzE3

    connect one end to the MacPro’s optical audio IN to the 828’s optical audio OUT

    On your DAW (audio editing software) you must choose the optical input as the source

    This can also be set in System Preferences so that even Garageband will automatically use this as the connection for inputs.
