The driver "snd-bcd2000" (for the Behringer BCD 2000 DJ controller) is not available in Fedora which prevents this hardware working. The relevant config option is CONFIG_SND_BCD2000. Please could it be enabled. It's a tiny module but essential for this hardware to do anything useful. I just rebuilt the current Fedora kernel-4.13.12-300.x86_64.fc27 with this option enabled and it works great. (There was a reference to this in bug #1204342, but it clearly didn't get enabled back then) Thanks!
I went ahead and enabled it on all branches. You'll see the bugzilla get updated when it shows up in a build.
Many thanks, and for the quick response! Much appreciated.
