Any class compliant audio interface should work.
We have used the Behringer U-Phoria UM2 (https://www.thomann.de/at/behringer_u_phoria_um2.htm) on single board computer, but the UMC1820 (https://www.thomann.de/at/behringer_umc1820.htm), which has 8 analog outputs, *should* work as well (not tested!)

it does very well!
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!

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

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!

I've used startech "7.1" interfaces (USB powered) with Pis. The "1" is the same electronics as teh "7" - it's really just an 8ch output. It has 1/8" connectors which won't age well but it's only $25 or so. I ended up buying 5 for an installation.

Yep. Three were Pi 1s which I think couldn't have powered more than one interface. I thin kyou could hang two or more off a Pi 4, but there won't be any way to sync the audio so you'll want to run separate instences of Pd or else enjoy the occasional audio resync-click.

Hi all, i have used this one: http://logilink.org/showproduct/UA0099.htm for installations. It has worked very stable literally running for years. It has 8 equivalent outputs and 2 inputs. It sells under different brand names with basically the same look and functionality. Audio quality with all such devices is low unless you source it with a separate filtered power supply (over powered hub). best, Thomas

Dear Jakob
As no one with more directly useful experience has piped up, I will say that I have been using the Gigaport eX with a Linux box for a couple of days and haven’t needed any tweaks or experienced any problems. It is not the loudest DAC, but it does sound pretty good.
I don’t have a pi to test it on, I am afraid.

i'm not adding anything to the problem solution, but i would like to stress that (from all the reports i heard; and also based on this thread
- see for instances Josh's reply), that "class-compliance" is not a
*sufficient* condition with older RPis (RPi1-RPi2; and i think RPi3 as well) as these have a somewhat broken USB-controller.
since jakob's target systems are *explicitly* RPi2s and RPi3s, i don't think that all those "it's class compliant, so it should work" comments are especially helpful.
the interesting question really is: can anybody recommend audio interfaces that they have *successfully worked with on the RPi2/RPi3* hardware platforms. without replacing the hardware specs with "a linux system running on an x86_64 processor in an ATX-motherboard with a 200W PSU".

Hi Oliver, The fact that you used those esi products successfully on rp2 and 3 makes it *i think* promising that the gigaport ex works, too!
The gigaport hd+ has sufficient outputs for my use case, but what makes me want to buy the gigaport ex instead, is the fact that the gigaport hd+ only supports 44.1khz/16bit when writing on 8 outputs. In the description of the gigaport hd+ they say that the gigaport ex is an advanced model with better audio quality.
Indeed in the description of the gigaport ex, it says that it supports 192khz/24bit „on all output channels“. Im just wondering if a raspi 2 or 3 can handle this:) If a raspi 4 could, i wouldnt mind to buy one.

From my experience, the issue is mostly about full-duplex. I managed to successfully use all sorts of cheap class-compliant audio interfaces with the RPi3, but I only ever needed audio output. I never had luck getting full duplex to work in Pd - which I didn't need in the end, so I didn't tried too hard.

been using the Gigaport eX with a Linux box for a couple of days and haven’t needed
i'm not adding anything to the problem solution, but i would like to stress that (from all the reports i heard; and also based on this thread - see for instances Josh's reply), that "class-compliance" is not a *sufficient* condition with older RPis (RPi1-RPi2; and i think RPi3 as well) as these have a somewhat broken USB-controller.
since jakob's target systems are *explicitly* RPi2s and RPi3s, i don't think that all those "it's class compliant, so it should work" comments are especially helpful.
the interesting question really is: can anybody recommend audio interfaces that they have *successfully worked with on the RPi2/RPi3* hardware platforms. without replacing the hardware specs with "a linux system running on an x86_64 processor in an ATX-motherboard with a 200W PSU".

Hi Matthew, Thanks for your message! I think that when you are on linux and its working fine there, it makes it more promising for the pi, too:)
Best, jakob

Dear Jakob
As no one with more directly useful experience has piped up, I will say that I have been using the Gigaport eX with a Linux box for a couple of days and haven’t needed any tweaks or experienced any problems. It is not the loudest DAC, but it does sound pretty good.
I don’t have a pi to test it on, I am afraid.
Best

I'm getting a brand new rockpro64 but it will be some time before it gets here as it's coming from China. It's a little bit more than the rpi but not by much (twice the price is still peanuts compared to the rest of the single board space compared to features) and it actually has four i2s connectors (four stereo pairs, making direct connected ADAT possible) plus a true onboard codec carrying both spdif and analog, pci-e, and hexacore (a72/53) with quad core mali 860 for 80 bucks for the 4 gig model... and no weird Broadcom hardware gotchas.
If i can get reliable multi-channel audio with it, i'll ping this thread again as it might be useful for someone else.

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?
