Description Choose an audio source device by index, setting it as the active audio recording source for the specified category. Parameters Playback [in] TRUE: Within the playback audio source category, which typically includes audio output devices like speakers and headphones. FALSE: Within the recording audio source category, which typically includes audio input devices like microphones and line-ins. Index [in] The specified index for the audio source device, ranging from 0 to the device count - 1. Return Value If an audio source device is selected successfully, the return value is TRUE. Otherwise, the return value is FALSE. Remarks Use this function to choose an audio source device by index, setting it as the active audio recording source for the specified category. If the index is greater than or equal to 0 and less than the device count, the respective audio source device is selected. If the index is less than 0, the system's default audio source device is chosen. If these conditions are not met, no device will be active for audio recording in the specified category. By default, only the system's default audio playback device is active. You are permitted to change the active audio source device even during the recording process. To check the index of the currently selected device in the specified audio source category, call ScnLib_GetSelectedAudioSourceDevice(). To adjust the system's default audio source devices, call ScnLib_ConfigureAudioSourceDevices().
