Hello.
This patchset add support for scenario management, aka use cases, in alsa-lib and example programs in alsa-utils. It allows to adjust the current audio kcontrol settings from a prespective of a changed use case like the switch from listening to music on your phone to an incoming phone call and back.
Great, I've been waiting for this :)
To achieve this it offers control aliasing for playback, capture master and switch as well as the option to post- and prefix a sequence of control changes avoiding pops and other unwanted noise.
This is of course not meant to replace gstreamer, PulseAudio or a sound server, but is meant to work in tandem with such audio software. We think alsa-lib is the best place for this as it will be used on small embedded system which only use alsa from the full stack of audio libs in linux. We see potential for desktop usage as well though.
Agreed. If any need, I can merge it to salsa-lib, too.
thanks,
Takashi
