Freewheel mode is implemented by switching from the (audio + freewheel) driver to the freewheel driver only:
|
|
241 |
||
242 |
- "global" connection state is saved
|
|
243 |
- all audio driver ports are deconnected, thus there is no more dependancies with the audio driver
|
|
244 |
- the freewheel driver will be synchronized with the end of graph execution : all clients are connected to the freewheel driver
|
|
245 |
- the freewheel driver becomes the "master"
|
|
246 |
||
247 |
Normal mode is restored with the connections state valid before freewheel mode was done. Thus one consider that
|
|
248 |
no graph state change can be done during freewheel mode.
