Hello,
With the following configuration : Ubuntu 16.04 Pd-0.47.0
I need to find a solution to send sounds on 16 different speakers. What is your advice regarding the purchase of USB sound cards under Linux with this configuration ? For you, which sound cards are more willing to do this job ?
I'm running Ubuntu 16.04 and I have an RME UCX that I pretty much love. It's got 8 analog outs built into the device (well, 7 and 8 are mashed together in the form of a stereo quarter inch out) but then you get 8 more with ADAT and 2 with SPDIF. The UCX has a big brother UFX that has even more outs. I use my UCX with the JACK Audio Connection Kit and then use Pure Data (or SuperCollider, or Ardour, or Audacity, or,.. pretty much anything) to talk to JACK. JACK is basically a middle man between your soundcard and everything else and it works great.
Well, pretty much all you need is a class compliant audio interface so be on the lookout for those. Unfortunately, audio interface companies don't like to make drivers for Linux but with the interface being class compliant, that doesn't matter.I think it was mentioned earlier that the Focusrite Scarlett 18i20 is an option. There's a handful of them out there.. hope this helps!
