The Auditioner is not part of the session route-list and the auditioner route's I/O latency is never updated. Session::process_audition() does not handle pre-roll either, so it need to be zeroed, otherwise Route::roll skips samples. This has lead to initial samples being skipped, IFF the auditioner's output-port had non-zero latency. Since private port-latencies are usually only set for routes in the route-list, and _remaining_latency_preroll is reset at transport-stop, this *usually* worked... Last but not least, MIDI notes need to be resolved when seeking.
