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

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
```
Here is the **`flutter doctor`** summary:
