Help! My Discord bot won’t play sound

I’m working on a Discord bot for my friend group. It’s supposed to play music but it’s not working right. I’ve tried different methods to play audio using ffmpeg. Below is a revised version of my code:

async def play_audio(msg):
    voice_channel = await msg.author.voice.channel.connect()
    print(voice_channel.is_playing())
    ffmpeg_settings = {
        'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5',
        'options': '-vn'
    }
    voice_channel.play(discord.FFmpegPCMAudio(source='mysong.mp3', **ffmpeg_settings))

The bot enters the voice channel and then immediately disconnects. The terminal displays this message:

discord.player ffmpeg process 18792 successfully terminated with return code of 2880417800

I’ve experimented with both YouTube videos and local audio files. I even set the ffmpeg path explicitly and enabled all intents, but nothing has resolved the issue. Is it possible that a firewall or another configuration is causing the problem?

hey man, have u tried checking ur bot’s voice state? sometimes the bot thinks its still in a channel when its not. try adding if msg.guild.voice_client: await msg.guild.voice_client.disconnect() before connecting. also make sure ur using the latest discord.py version cuz older ones can be buggy with audio stuff

Have you checked if your bot has the correct intents enabled? Discord recently made changes requiring specific intents for certain functionalities. For voice-related features, you need the ‘voice_states’ intent.

Also, ensure your Discord.py version is up-to-date. Older versions may have compatibility issues with recent Discord API changes.

Another thing to try is using a context manager for the voice client:

async with msg.author.voice.channel.connect() as vc:
    vc.play(discord.FFmpegPCMAudio('mysong.mp3', **ffmpeg_settings))
    while vc.is_playing():
        await asyncio.sleep(1)

This approach can help manage the connection more reliably. If issues persist, consider logging more details about the error to pinpoint the exact failure point.

I’ve encountered similar issues with Discord bots and audio playback. One thing that helped me was ensuring the FFmpeg executable was properly installed and accessible in the system PATH. Sometimes, even when you think it’s set up correctly, there can be conflicts.

Another potential fix is to add a small delay after connecting to the voice channel before attempting to play audio. The connection might not be fully established when you try to play immediately. You could try something like:

voice_channel = await msg.author.voice.channel.connect()
await asyncio.sleep(1)  # Wait for 1 second
voice_channel.play(discord.FFmpegPCMAudio(source='mysong.mp3', **ffmpeg_settings))

Also, double-check your Discord bot’s permissions in your server settings. Ensure it has the necessary permissions to join voice channels and play audio. Sometimes these can get overlooked.

If none of these work, you might want to try a different audio source to rule out any issues with the specific file you’re using. Let me know if any of these suggestions help!
