5.1 is broken with Apple Music, both directly through the Digiface and via an aggregate device.

I saw RME has an update for Digiface USB, worth a try? (2022 04 04)

And surround works as expected (for 5.1) with the TV app, including with the Digiface USB.

Curious about your settings of Audio MIDI Setup, would you post the screenshot of the aggregate device?

an additional bug in AMS, where channel 3 is mislabelled channel 1 in the pop-up menu

It's not mislabeled (also not a bug). You (or someone) put "1" into ch3 so the label becomes 1.😆

You can edit the channel label as you like.

@wisechoiceHere's what I found: if you want to use Quadraphonic, CoreAudio default is ch1, 2, 5 and 6. You can't change this in AMS (AMS is just an organizer). If you connect 2 DACs and want to set as Quadraphonic, you'll prob never hear sound comes out from the DAC which designated to ch3 and 4.

In this case, I'd suggest using Loopback to route the channel to the correct output.
