Type:REG_DWORD
A percentage value (0 to 100) that will be used as the volume threshold. If this registry setting exists, and the currently active audio output device master volume is set below this level and/or muted, then when the device is being charged, this service will mute all users' active audio sessions, raise the master volume of the active audio output, play the specified charging sound, and then restore back the master volume together and unmute the active audio sessions.
- Charging audio will always be played in the currently active audio output device.
