The range is 0,255. @note Start an audio-device test by calling startAudioPlaybackDeviceTest:interval:{@link #ByteRTCAudioDeviceManager#startAudioPlaybackDeviceTest:interval} or startAudioDeviceRecordTest:{@link #ByteRTCAudioDeviceManager#startAudioDeviceRecordTest} will register this callback for regular notification on playing volume. You can set the time interval between each callback by passing a proper value when calling the API above.
