Name of the current device for audio input (see [method get_device_list]). On systems with multiple audio inputs (such as analog, USB and HDMI audio), this can be used to select the audio input device. The value [code]"Default"[/code] will record audio on the system-wide default audio input. If an invalid device name is set, the value will be reverted back to [code]"Default"[/code].

Name of the current device for audio output (see [method get_device_list]). On systems with multiple audio outputs (such as analog, USB and HDMI audio), this can be used to select the audio output device. The value [code]"Default"[/code] will play audio on the system-wide default audio output. If an invalid device name is set, the value will be reverted back to [code]"Default"[/code].
