Discord bot enters voice channel but fails to play audio

I’ve created a Discord bot for my server that should join voice calls and queue up songs, but it doesn’t play any audio. Although the bot joins the channel and loads songs into the queue, no sound is output and there are no console errors.

Here’s an updated version of my code:

import discord
from discord.ext import commands
from youtube_dl import YoutubeDL

class MusicBot(commands.Cog):
    def __init__(self, bot):
        self.bot = bot
        self.now_playing = False
        self.song_list = []
        self.voice_client = None

    async def play_song(self, ctx):
        if self.song_list:
            self.now_playing = True
            song_url = self.song_list[0][0]['url']
            self.voice_client.play(discord.FFmpegPCMAudio(song_url), after=lambda e: self.play_next())
            self.song_list.pop(0)
        else:
            self.now_playing = False

    @commands.command()
    async def add(self, ctx, *, query):
        voice_channel = ctx.author.voice.channel
        if voice_channel:
            song = self.find_song(query)
            if song:
                self.song_list.append([song, voice_channel])
                await ctx.send('Song added to queue')
                if not self.now_playing:
                    await self.play_song(ctx)
            else:
                await ctx.send('Song not found')
        else:
            await ctx.send('Join a voice channel first')

# Other commands like pause, resume, and skip would be here

I’m new to Discord bots, so any suggestions to help me resolve this issue would be greatly appreciated.

I’ve encountered a similar issue before and found that the problem often lies in missing dependencies. It appears that FFmpeg is not installed or properly configured, which stops the bot from processing and outputting the audio stream. I suggest downloading FFmpeg from its official website and making sure it is added to your system’s PATH environment variable. Also, verify that the PyNaCl library is installed using pip. Lastly, confirm that your bot has the required permissions to speak in the designated voice channel.

hey man, i had the same issue. make sure u’ve got the right intents enabled for ur bot. also, check if ur using the correct FFMPEG options. sometimes the default ones don’t work great. try adding some extra options like ‘-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5’ to ur FFmpegPCMAudio call. that fixed it for me!

Having dealt with Discord bots myself, I can relate to your frustration. One thing that stood out to me is the absence of error handling in your code. I’d recommend wrapping your audio playback in a try-except block to catch any exceptions that might be occurring silently.

Also, make sure you’re using the latest version of discord.py, as older versions had issues with voice functionality. Additionally, double-check your bot’s token and ensure it has the necessary permissions in your server.

If the problem persists, you might want to look into using a different audio source. I’ve had success with youtube-dl for downloading and FFmpeg for playing. It’s a bit more complex to set up, but it’s generally more reliable for audio playback in Discord bots.

Lastly, don’t forget to close the voice client when you’re done to free up resources. Good luck with your bot!
