                -Recording        # Outputs the default recording device as <AudioDevice>
                -RecordingMute    # Outputs the default recording device's mute state as <bool>
                -RecordingVolume  # Outputs the default recording device's volume level on 100 as <float>

Set-AudioDevice <AudioDevice>             # Sets the default playback/recording device to the given <AudioDevice>, can be piped
                -ID <string>              # Sets the default playback/recording device to the device with the ID corresponding to the given <string>
                -Index <int>              # Sets the default playback/recording device to the device with the Index corresponding to the given <int>
                -PlaybackMute <bool>      # Sets the default playback device's mute state to the given <bool>
                -PlaybackMuteToggle       # Toggles the default playback device's mute state
                -PlaybackVolume <float>   # Sets the default playback device's volume level on 100 to the given <float>
                -RecordingMute <bool>     # Sets the default recording device's mute state to the given <bool>

                -RecordingVolume <float>  # Sets the default recording device's volume level on 100 to the given <float>

Write-AudioDevice -PlaybackMeter  # Writes the default playback device's power output on 100 as a meter
                  -PlaybackSteam  # Writes the default playback device's power output on 100 as a stream of <int>
                  -RecordingMeter # Writes the default recording device's power output on 100 as a meter
                  -RecordingSteam # Writes the default recording device's power output on 100 as a stream of <int>
