use AudioEffect to use GainNode to amplify gain value

[jaysinh01]

Hey I need help with adjusting gain value in my audio stream.

        const audioContext = mergerState.getAudioContext(); // mergerState is an instance of VideoStreamMerger()
        const gainNode = audioContext.createGain();
        mergerState.addStream(stream, 
          { 
          audioEffect: function (source, dest) {
            source.connect(gainNode)
            gainNode.connect(dest)
          }
        });

Then, I am calling the following line in a different function.

gainNode.gain.value = 1.5;

Setting gain value to 1.5 does not change stream's gain value in resulting stream.

Goal: I am trying to dynamically change the audio stream's gain value. Anyone else able to use gainNode on audioEffect?
