Discord Bot that Plays an Audio File When Someone Joins

Question

I would like the bot to join a voice channel when someone joins and then play a sound file.

So far, I've gotten the bot to join the voice channel but it just doesn't play the sound and no errors show so I don't really know what is going wrong.

const Discord = require('discord.js');
const bot = new Discord.Client();
bot.login('BOT TOKEN');

bot.on('voiceStateUpdate', (oldMember, newMember) => {
  let newUserChannel = newMember.voiceChannel
  let oldUserChannel = oldMember.voiceChannel
  let textChannel = oldMember.guild.channels.get('TEXTCHANNEL ID')

  if(oldUserChannel === undefined && newUserChannel !== undefined) {

    if (newMember.id === 'MEMEBER ID')         //Member 1
    {   
       newUserChannel.join()
       .then(connection => {
          console.log("Joined voice channel!");
          const dispatcher = connection.playFile("C:\Users\NAME\Documents\Welcome_Bot\music\bossman.mp3");

          dispatcher.on("end", end => {newUserChannel.leave()});
       })
        .catch(console.error);

    }
      else if (newMember.id === 'MEMEBER ID')       //Member 2
      {
       textChannel.send('Hello Member 2')
      }
        else if (newMember.id === 'MEMEBER ID')      //Member 3
        {
          textChannel.send('Hello Member 3')
        }
           else                                      //Random
           {
             textChannel.send("Hello") 
           } 
  } 
});

I believe your issue is that the bot isn't actually joining the channel before you call the dispatcher. The bot needs to be told to enter the channel before you call the dispatcher. Havn't worked on audio in a while but I believe that connection.join() right above your dispatcher would work. You may need to .then() to ensure it dosn't initilize the dispatcher before the bot joins the channel.
