I'm setting up an interactive art installation.
I want to use Raspberry Pi4 as a stand-alone device,
I'm using Supercollider (open-source audio synthesis sw) for the multi-channel composition (6 channels or 5.1).
I would like to ask which is the most simple and robust way to go:
1. USB external soundcard. Which are the most compatible and tested with Pi (with the right drivers)
2. HDMI Audio Extractor, for example:

Has anyone experience with this kind of devices. Do they work? Are they plug and play?
3. add-on shields:
a. Audio Injector Octo sound card.

b. X6000K-8.0CH Expansion Board
Unfortunately, they have stopped producing them. They are upgrading them for Pi4. They will be ready in a few months.
Has anyone tried any of these?
Any suggestions are extremely valuable.
Thank you in advance
