Bot hangs on VoiceChannel.connect and eventually disconnects 25 seconds later

[j-silv]

Summary

Calling ctx.author.voice.channel.connect() gets the bot to join the voice channel, but then it doesn't respond to the slash command and then exits the voice channel 25 seconds later

Reproduction Steps

Follow the tutorial here, but simplify the code to only call the voice.channel.connect() method. Run the slash command record.

Minimal Reproducible Code

import discord
import os
from dotenv import load_dotenv

load_dotenv() # load all the variables from the env file
connections = {}

intents = discord.Intents.default()
intents.voice_states = True

bot = discord.Bot(intents=intents)

@bot.event
async def on_ready():
    print(f"{bot.user} is ready and online!")

@bot.command()
async def record(ctx):  # If you're using commands.Bot, this will also work.
    voice = ctx.author.voice

    if not voice:
        await ctx.respond("You aren't in a voice channel!")

    vc = await voice.channel.connect()  # Connect to the voice channel the author is in.
    connections.update({ctx.guild.id: vc})  # Updating the cache with the guild and channel.

    await ctx.respond("Started recording!")
    
bot.run(os.getenv('DISCORD_TOKEN')) # run the bot with the token

Expected Results

When the user who sent the slash command is in the voice channel, the bot should connect and then respond with "Started recording!". The bot should then stay in the voice channel.

Actual Results

The bot does join the voice channel, but disconnects after 25 seconds (even when there is speaking activity from the user). Once the bot disconnects, the voice.channel.connect() method returns and then we get a 404 Not Found Unknown interaction error. Additionally, while the bot is hanging on the connect method, after 3 seconds it sends a The application did not respond red error message in the Discord UI.

bot is ready and online!

Additional Context

I've tested this with both of the following installation methods and the results are the same:

pip install "py-cord[voice]"
python3 -m pip install "git+https://github.com/Pycord-Development/pycord#egg=py-cord[voice]"

Issue #2310 seemed similar to this, but I'm not sure if it's the same cause. Is it necessary to have the voice scope when generating the OAuth2 URL? If so, then this might be the issue, because the discord documentation says:

voice scope: allows your app to connect to voice on user's behalf and see all the voice members - requires Discord approval

However I thought that was unrelated to the bot...

[Restitutor]

Have you tried this fix? #2812 I had a similar but unrelated voice issue which this resolved.
