Remove various checks, add assert() for now (perhaps some old sessions?)
This fixes an off-by one issue when adding tracks (presentation
info order in add_routes_inner)
* requested_physical_in/out was unused
* input/output Autoconnect just overrides Preference/Config
(can be done by a template script)
* master_out_channels is kept for compatibility (allow to create
new empty session)
It isn't 100% clear that we should use the list's data lock, but it seems quite likely
that this is the correct design, because of the interlock between data being present
and automation state
Prepare for a method consistent with access_action():
* separate group + action names
* no action string parsing overhead.
* no fatal, abort () call for invalid actions
This hopefully fixes an issue with port-registration (new session)
being skipped because PortAudioBackend::available() still false
until the first callback.
The root-cause is likely PortAudio backend specific async
port-registration, re-establish ports after session creation and
after the first callback and it's apparently a race-condition:
crash is not 100% reproducible.
