..or new ports are available. but even if the number of ports stays the

same, the actual pinout may be different.
Currently all connections to and from the backend are lost when

switching backends. JACKd (currently) has no clue and it's the only sane

thing to do.
Here's a bash script that can re-connect or re-map connections after

switching backends. It's a bit hacky but works for me.
