DiscordJS bot connecting to vocal channel but music is not playing [duplicate] - discord.js

Question

const Discord = require("discord.js");
require('dotenv').config();
const { joinVoiceChannel, createAudioPlayer, createAudioResource, AudioPlayerStatus } = require('#discordjs/voice');
const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"], partials: ["CHANNEL"] });
const player = createAudioPlayer();
var channelsToMonitor = ['902193996355485778'];
function joinChannel(channel) {
const connection = joinVoiceChannel({
channelId: channel.id,
guildId: channel.guild.id,
adapterCreator: channel.guild.voiceAdapterCreator,
});
return connection;
}
function playAudio(connection) {
// Subscribe the connection to the audio player (will play audio on the voice connection)
const resource = createAudioResource('./music/', 'alarm.mp3');
resource.volume = 1;
player.play(resource);
connection.subscribe(player);
player.on(AudioPlayerStatus.Playing, () => {
console.log('ALRM');
});
}
client.on('ready', () => {
console.log('ready');
})
client.on('messageCreate', async msg => {
try {
if (channelsToMonitor.indexOf(msg.channel.id) !== -1) {
if (msg.content == 'GOGOGO') {
const guild = client.guilds.cache.get("857332849119723520");
const channel = guild.channels.cache.get("921415774676058152");
if (!channel) return console.error("The channel does not exist!");
var connection = joinChannel(channel);
await playAudio(connection);
}
} else {
if (msg.author.bot) return;
}
} catch (err) {
console.error(err.message);
}
});
client.login(process.env.DISCORD_TOKEN_2);
I have set this up from the docs
And I cannot find why no audio is coming out! The bot joins the channel and says it's playing when I use console.log(player) but for some reason, it is deafened and doesn't play any sound.

Bots now join with self deaf by default. Provide the selfDeaf field to stop this:
const connection = joinVoiceChannel({
channelId: channel.id,
guildId: channel.guild.id,
adapterCreator: channel.guild.voiceAdapterCreator,
selfDeaf: false,
selfMute: false // this may also be needed
})
