HRw: you're facing a really heavy known problem from the gregale (2006): Dbus version is quite old and it takes really a while to the "play" command to be properly executed and return to canola. So indeed it takes a long time.

Those kind of issues made us drop support for those devices / firmware versions:
we cannot upgrade it's dbus (it would break the basic software) and then we are stuck with the problem.

Sorry for the trouble, but this problem is way beyond our capabilities for now. Maybe we could improve it, but we are focused on chinook and diablo only.
