node js ffmpeg hls stream sound is repeating and overlays to each other

Question

I'm trying to stream video and audio with rtmp and I'm stack with problem that I hear sound which overlays to each other and always repeating. But my target is to not repeating and overlay audio to each other. Parsing hls performs with hls.js

This is my ffmpeg config which creates 4 streaming files which includes in master file index.m3u8

let argv = ['-y', '-i', inPath];
  Array.prototype.push.apply(argv, [
    '-filter_complex', '[0:v]split=4[v1][v2][v3][v4];[v1]copy[v1out];[v2]scale=w=1280:h=720[v2out];[v3]scale=w=800:h=480[v3out];[v4]scale=w=640:h=360[v4out]',

  this.ffmpeg_exec = spawn(this.conf.ffmpeg, argv)
