adjustRecordingSignalVolume() not increasing the sound signal volume properly for setAudioProfile(scenario: AudioScenarioType.audioScenarioChatroom)

[mehedi4958]

I am using: agora_rtc_engine: ^6.5.2.

It is creating the video streaming completely fine. I have also set the AudioProfile, AdvancedAudioOptions, and adjustRecordingSignalVolume to enhance the audio quality. Though changing adjustRecordingSignalVolume() is working for all other AudioScenarioType in AudioProfile, it seems not to increase the input signal volume for setAudioProfile(scenario: AudioScenarioType.audioScenarioChatroom).

Here is my code snippet:

await _engine.setAudioProfile(
      profile: AudioProfileType.audioProfileMusicHighQualityStereo,
      scenario: AudioScenarioType.audioScenarioChatroom, // working properly for other audio scenarios
    );
    await _engine.setAdvancedAudioOptions(
        options: AdvancedAudioOptions(audioProcessingChannels: 1));
    await _engine.adjustRecordingSignalVolume(400); // increasing the signal volume not working properly only for AudioScenarioType.audioScenarioChatroom
