Well, I guess there is more software like that, any music player for
example.  I don't think this is a good reason for qemu to have
non-standard behavior.  If you want qemu autoconnect, you can use the
connect-ports option.

Beside that I'd expect the patch bay software is able to remember the
routing configuration per application, so the setup would be a one-time
thing you don't have to re-do on every qemu launch.  Not fully sure this
is actually the case though, I'm not a regular jack user.

take care,
