On my UbuntuStudio 16.04 (4.4.0-36-lowlatency) the streaming interfaces (16xin & 8xout) works perfect with the stock driver / JACK. The intention of my custom snd-usb-audio is to offer the build-in DSP features of the US-16x08. So I didn't made changes to the streaming interfaces but added some mixer quirks to the stock driver. Add. I did coded a custom mixer application (QT5) to control the EQ and compressor function via those new mixer interfaces. ranokio wrote If you have problems with the streaming interfaces, I guess my driver wont help you. You may investigate the diff-file based on my changes in Ubuntu 16.04 which you'll find here <http://www.paraair.de/snd-usb-audio/us16x08.diff> . Note! Because I'd never investigate Fedora sources, I assume you should NOT apply the patch to your kernel source directly.
