display_manager-audio_output: [bool]

@on if there is a device to play sound on. The slot is @default until the first request, which starts the audio subsystem. From then on the value follows the playback devices that are added and removed. Use this to make sound optional, as playing a sound or audio_stream without a device prints an error.
