how do I keep playing audio file in browser

Question

I am trying to play audio clips of audio receieved from server through socketio. The code works but on the first audio clip recieved is played, any clip recieved afterwards are not played. I confirmed their reciept but I don't know why it only plays the first received audio file.

   socketio.on('audio_playback_results', function (data) {
        console.log("I recieved an audio playback! ",data);
        playOutput(data);
    });


    function playOutput(arrayBuffer){
        let audioContext = new AudioContext();
        let outputSource;
        try {
            if(arrayBuffer.byteLength > 0){
                console.log(arrayBuffer.byteLength);
                audioContext.decodeAudioData(arrayBuffer,
                function(buffer){
                    audioContext.resume();
                    outputSource = audioContext.createBufferSource();
                    outputSource.connect(audioContext.destination);
                    outputSource.buffer = buffer;
                    outputSource.start(0);
                },
                function(){
                    console.log(`playoutput PLAYING OUTPUT ARGUMMENT ${arguments}`);

                    // console.log(arguments);
                });
            }
        } catch(e) {

            console.log(`ERORRR PLAYING OUTPUT ${e}`);
        }
    }

i perform a text to audiobuffer on server side and then stream it back to client side.

async function textToAudioBuffer(text) {

  requestTTS.input = { text: text }; // text or SSML
    const response = await ttsClient.synthesizeSpeech(requestTTS);
    console.log("RESPONSE @ ttsClient, textToAudioBuffer() : ", response[0].audioContent)

    var results = response[0].audioContent

     io.emit('audio_playback_results', results);


  return response[0].audioContent;
}

what is causing it not to play audio clip recieved after the first one and how can I fix this ?
