Hello all, hello list,
I am not sure whether this is the correct list, since it's not strictly an
ALSA affair (fw to kernel-devel)=2E Recent progress on driver support for
Pioneer devices encouraged me to dissect USB communication with an
Allen&Heath Xone43C, a mixer with USB interface=2E It does feature 16 chan=
nels
(8 in, 8 out), but only 4 (2 in, 2 out) show up, 2 of which remain automag=
ically
silent=2E There is no linux driver yet, and maybe I can help?
