-/* General power management rules:
- *
- *   When SUSPENDED we close the audio device.
- *
- *   We make no difference between IDLE and RUNNING in our handling.
- *
- *   As long as we are in RUNNING/IDLE state we will *always* write data to
- *   the device. If none is avilable from the inputs, we write silence
- *   instead.
- *
- *   If power should be saved on IDLE module-suspend-on-idle should be used.
