UpdateAudioOutput (Unreal Engine)

- Declaration

static void UpdateAudioOutput(FCavrnusOutputDevice Device);

- Description

Sets which microphone the user wishes to use. Note that the FCavrnusOutputDevice provided to this function can only be acquired by calling FetchAudioOutputs to search for available microphones.

NOTE: This only affects the Cavrnus voice chat, not your application’s other sounds.

- Blueprint Sample

Sample is taken from WBP_AudioVideoWidget.uasset in the Plugin. AudioOutputDeviceResponse is a Blueprint array of FCavrnusOutputDevice instances that was provided earlier via Fetch Audio Outputs.
