I'm trying to use a couple of Behringer interfaces together: a FLOW8 mixer and UMC404HD interface.
The FLOW8 sends ten channels: eight physical plus another two for the main output.
The UMC404HD sends four.
Following the Multiple Devices instructions on the Jack Audio website I've created an .asoundrc file assigning the FLOW8 to ten channels (0-9) and the UMC404HD to four (10-13).
I assumed that a new device would appear - 'merge' - in Jack etc but I can't see one.
Can anybody spot what I'm doing wrong? I'd guess it's something in the .asoundrc file but really don't know.
I think these are all the relevant bits of info:
The .asoundrc file:
