Audio mixing (audiomixer.h)
Functions to interact with the audio mixer.
The audio mixer service reads audio mixer change events, such as when the volume level or gain of mixer channels changes. You can also use the audio mixer service to set and get different audio attributes, such as volume, gain, and mute status.
For example, using the audio mixer service allows an application to receive notifications when a headset is present, or when the speaker volume is muted. The application can also set headset volume, speaker volume, and so on.
You should call the function audiodevice_get_info() to verify that the audio device you want to use exists on the platform. If the function returns BPS_FAILURE, then the specified audiodevice_device_t audio device does not exist and using the unavailable audio device type may result in program error or termination.
