Functions

canHandleDeviceSwitch

fun canHandleDeviceSwitch(): Boolean

clearUsbDeviceSelection

fun clearUsbDeviceSelection()

Clears the USB device selection, restoring default audio routing.

fun disable(fromUser: Boolean = true)

Disable the audio track. Audio is still captured, but not send. This allows for the "you are muted" toast to indicate you are talking while muted

fun listDevices(): StateFlow<List<StreamAudioDevice>>

List the devices, returns a stateflow with audio devices

fun listUsbDevices(): StateFlow<List<UsbAudioInputDevice>>

Lists all detected USB input devices.

fun pause(fromUser: Boolean = true)

fun resume(fromUser: Boolean = true)

fun select(device: StreamAudioDevice?)

Select a specific device

selectUsbDevice

fun selectUsbDevice(device: UsbAudioInputDevice?): Boolean

Selects a USB input device as the preferred audio input source.

setAudioBitrateProfile

suspend fun setAudioBitrateProfile(profile: ERROR CLASS: Symbol not found for AudioBitrateProfile): Result<Unit>

Sets the audio bitrate profile, before joining or on a running call, so a broadcaster who starts playing music can switch to MUSIC_HIGH_QUALITY without rejoining.

fun setEnabled(enabled: Boolean, fromUser: Boolean = true)

Enable or disable the microphone

setupUsbDeviceDetection

fun setupUsbDeviceDetection()

Sets up USB audio device detection using Android's AudioDeviceCallback.
