Hi @friendtree16,

I can't hear the video sound from the web application.

I am sorry about this. The problem is that the example app doesn't support mixing of ReplayKit audio yet. If you only want the app audio and not the mic you can get it by changing this line of code.

    static let kAudioSampleType = RPSampleBufferType.audioApp

• Ref to: Example of mixing the sampleBuffer of appAudio provided by RPScreenRecorder or BroadcastExtenion. #595

Best,
Chris
