I got the following configuration:
7" Pi display
Pifi Dac+ V2
Everything loads fine and looks good, no errors, Jack starts as normal.
However, if I plug in a LPK25 Akai USB midi-keyboard, Jack refuses to start.
Looks like the LPK takes over position 0 as a sound card in Alsa, and the Pifi are moved to 1. Jack still tries to talk to 0 with no success.
Are there any solutions to this?
