Read stream feedback

@tableofcontents

Objectifs:

• Implement a feedback.

Bases:

A feedback is a stream that is generated by an output.

To get a feedback this is the same implementation of an input and link it on an output.

What change:

//Get the generic feedback on speaker:
interface = manager->createFeedback(48000,
                                    etk::Vector<audio::channel>(),
                                    audio::format_int16,
                                    "speaker");

Note: Input interface does not provide feedback.
