| D | dapm.rst | 2 Dynamic Audio Power Management for Portable Devices
8 Dynamic Audio Power Management (DAPM) is designed to allow portable
9 Linux devices to use the minimum amount of power within the audio
11 management frameworks and, as such, can easily co-exist with them.
16 switching decisions based upon any audio stream (capture/playback)
17 activity and audio mixer settings within the device.
19 DAPM is based on two basic elements, called widgets and routes:
21 * a **widget** is every part of the audio hardware that can be enabled by
23 * a **route** is an interconnection between widgets that exists when sound
