Tweak engine startup, initial silence

Multimedia / Ardour - Robin Gareus [] - 30 March 2020 13:20 EDT

This can help when running with very low latency and the initial process callback is [indirectly] expensive.

E.g. load a heavy session the a RPi4, initial setup can pull in a lot of data, which blocks the bus.

In particular with the ALSA backend this can lead to poll timeout which effectively stops the backend.
