11 management frameworks and, as such, can easily co-exist with them.
16 switching decisions based upon any audio stream (capture/playback)
19 DAPM is based on two basic elements, called widgets and routes:

121 	Inter widget audio data buffer within a DSP.
123 	DSP internal scheduler that schedules component/pipeline processing
128 	Sample Rate Converter within DSP or CODEC
130 	Asynchronous Sample Rate Converter within DSP or CODEC
139 (Widgets are defined in include/sound/soc-dapm.h)
