How can I get rid of mute noise?

[Cjsghkd]

mixer = MediaMixer(context)
session = StreamSession
            .Builder(context, url.toUri())
            .build()
audioRecordSource = AudioRecordSource(context)
audioRecordSource?.let {
    it.sampleRate = 48000
    it.channel = 1
    it.audioSource = WowzaGlovalVariable.AUDIO_SOURCE
    it.isMuted = !isMicOn
}            

mixer?.attachAudio(0, audioRecordSource)
mixer?.registerOutput(session?.stream)         

I'm setting up the three global variables "mixer," "session," and "audioRecordSource" and broadcasting them, as shown in the current code.

However, I want to add a mute function:

audioRecordSource?.isMuted = !isMicOn

When I try to apply this code, when the "isMuted" property is set to true, the actual broadcast sound is muted, but I still hear a noise. Did I change the wrong property?

Is this a technical issue, or am I using it incorrectly?
Could you please confirm?
