Hi Jakob,

I use an audio-injector:
http://www.audioinjector.net/

I have the ultra, 2 in-2 out, and it works well with an up-to-date raspbian. The octo, as you can imagine by the name, doe's what you need. Keep in mind they connects directly to GPIO, so you can't use them anymore. And AFAIR, you need to buy the ribbon connector separately.
Old Focusrite are known to work too
And I guess all class-compliant devices should work (???)

good luck!

Dear 0xFFriends,
I am looking for an usb audio interface that has at least 8 outputs so that I can have at least 4 stereo outputs from within pd. The challenge: I am on a raspberry pi (2 and 3). Does someone of you know about an audio interface that supplies this number of outputs AND works with a raspi?
 
Or is it possible to buy 4 cheap audio interfaces with 2 outputs each and use the simultaneously?
 
Best, Jakob
