As Christof said, Behringer devices work well. Even a XR18 (18in/10out + full per-channel DSP process, such as: gain/compress/gate/eq/fx-send/DCA...) works like a charm on a rPi!

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?
i used the "ESI Gigaport HD+ 8-Output" in a sound installation, and that was rock solid. worked even on a RPI 2 (out of the box as far as i remember)
you might want to consider an external power supply (an active usb hub) for the soundcard. and (since i was streaming an 8 channel wav file with [readsf~] i had to increase PD's audiobuffer and the playback blocksize for smooth playback (i put [readsf~] into a subpatch and used [block~ 2048 1 1] to achieve that - if i remember correctly).
Or is it possible to buy 4 cheap audio interfaces with 2 outputs each and use the simultaneously?
I would strongly advise against that
Best
Oliver
