2b4ac72e5d Add button to Engine Dialog to choose between Portaudio callback and blocking API 2016-02-11 12:15:07 +10:00
c0a843a905 fix device-list update concurrency issue.
It may happen that during push_state_to_backend() a device is
reconfigured in a way that triggers a "Device Changed" callback before
the engine is started. This callback can trigger a change to the
configuration that will be used when the engine is actually started.

This has been seen on OSX in conjunction with Aggregate Devices
(even if the aggregate is not used, but the device which is used
is also part of an aggregate) 

example: HW changed callback arrives, device-list is re-populated,
*A*irplay" is at the top of the list, Airplay supports only 44.1K,
Samplerate changes... later save also writes this new rate to the file.

ef0f13cb84 Stop engine when clicking back button in latency measurement tab of EngineControl dialog
The engine is started when you switch to latency measurement tab but it isn't
stopped if you just click the back button without measuring for latency.

cd4dd08931 Add EngineControl::stop_engine method to show errors when stopping engine
This replaces using ARDOUR_UI::disconnect_from_session which is only used by the
EngineControl class. ARDOUR_UI::disconnect_from_session also disconnects from
the AudioEngine::Halted signal which seems unnecessary as Halted is not emitted
when stopping the engine and calling update_sample_rate() which is already
handled when the AudioEngine::Stopped signal is emitted.

9626e0c413 Add "Refresh Devices" button in Audio Setup dialog for backends that support it
This allows the portaudio library to be reinitialized to pick up new devices
and changes to ASIO buffer changes made externally.

6bb51a26eb consolidate engine-dialog widget sensitivity logic.
Use a single function with the complete logic.

Since the callgraph is complex, there is internal state as well as GUI
state (different pages), do not rely on individual methods to get it
right.

A widget's sensitivity should only be controlled by one function.

a8daa36901 Use a union of all sample rates and buffer sizes for all devices in EngineControl
Using just the input device doesn't work in the case that the input device is
an invalid/None device

ab7cf8c7a7 Fix state restoration in EngineControl dialog for backends with driver selection
This also prevents backend_changed from being called more that once in the

2437bbbe23 Fix state restoration in Engine dialog for Backends with driver selection
Connect to the backend_combo changed signal after setting state as calling
backend_combo.set_active_text() in set_state was triggering backend_changed(),
which would then see the driver_combo had not been set and set it to the
incorrect value.

The value/name of the backend needs to be restored first then we can populate
the driver combo and set the correct active entry from the saved state. After
which backend_changed() will populate the device combo's etc so they can then
be set to the correct active values from the saved state.

d9f24a46aa Allow selection of input and output devices in EngineDialog for backends that support it
Some refactoring was necessary to avoid code duplication

Restoring of device state for input and output devices still doesn't work
correctly. I'm not quite sure what the issue is at this stage.

d2cbb28f79 Engine Dialog: fix various signal connections
connect/disconnect button was connected multiple times
Also the button allowed to start a backend with
invalid settings (after changing backend).

Q: does “Connect to” make sense? It’s redundant with 
“Apply”.

371bf59a94 for backends w/o control, save a fake state with only the "active" attribute.
This makes ardour start directly with external jack without asking if jack
was previously used. It also retains jackd settings if jackd was previously
started by ardour.
