Summary

As of latest master, my bot can't connect to a voice channel and play audio. This works fine on 2.3.2.

Reproduction Steps

1. Start the bot, with the attached Commands.Cog added.
2. Connect to voice.

Minimal Reproducible Code

class MinimalExample(commands.Cog):
    @commands.Cog.listener()
    async def on_voice_state_update(self, member, before, after):
        vc = member.guild.voice_client
        if member.id == self.bot.user.id:
            return  # Don't trigger on our own actions
        elif before.channel == after.channel:
            return  # Channel didn't change, so not a join or leave event
        elif not vc and after.channel:
            await self._connect(after.channel)

    async def _connect(self, channel):
        if channel.guild.voice_client is None:
            vc = await channel.connect()
            print(vc)

Expected Results

connect returns a voice_client with which I'm able to play audio.

Actual Results

connect never returns, and I get this debug log.

Intents

intents = discord.Intents.default()
intents.members = True
intents.message_content = True

I'm not entirely sure why discord is sending a second VOICE_SERVER_UPDATE event but it seems that's what's getting the code into a bad state. It doesn't seem to be related to joining from the event or from an automatic voice region channel. Does connecting work if it's simply called from a command, like so?

@commands.command()
async def join(self, ctx):
    if not ctx.voice:
        await ctx.author.voice.channel.join()

For reference, this is what my logs of connecting to voice look like.

@imayhaveborkedit Yes, it does.

Oct 29 '23 06:10 codeofdusk

I believe this is occuring because you have 2 instances of your bot running with this same on_voice_state_update listener. Can you double check you don't have 2 instances of your bot running?

Oct 29 '23 07:10 EvieePy

Can you double check you don't have 2 instances of your bot running?

@EvieePy I'm certain that I only have one instance running.

Oct 29 '23 07:10 codeofdusk

That was the only way I was able to reproduce this issue so far. I will keep trying, but in the mean time, you could reset your bots tokens just to be certain, as this should disconnect any stray instances running.

I think I can fix this specific issue for you but it's not much more than a band-aid fix unless I can figure out why you get two voice_server_update events. Regardless if multiple instances cause this issue for you or not, this wasn't something I tested when I wrote this code.

One other question, is the token value in both of those voice_server_update payloads the same?

Oct 29 '23 07:10 imayhaveborkedit

@imayhaveborkedit Yes, it is.

Oct 29 '23 08:10 codeofdusk

Any updates on this issue? I'm still able to reproduce it as of 425edd2e10b9be3d7799c0df0cd1d43a1a34654e.

I am having this issue as well.

I am also having this issue (Python 3.9.0, discord.py 2.0.1). Never seems to return from await channel.connect()

edit: ignore me, forcing discord.py to update to 2.3.2 via pip install -U discord.py[voice] fixed it
