ALSA Scenario Manager
Audio Scenario or Use Case Manager
The ALSA scenario manager is a LGPL library designed to allow high level control of audio scenarios or use cases in sound device hardware. It is intended to be used by applications to change the hardware audio scenario of a device in a generic and portable manner. e.g. a dialer application may want to set a "GSM phone call" scenario or a media player may want to set a "playback via headphones" scenario.
This library is currently work in progress. It is however intended to be merged in with alsa-lib/salsa once it has become mature.
