Bot can't connect to voice chat

[PWDSerialgamer07]

Summary

When trying to connect to a channel, the bot will hang for some time, then disconnect.

Reproduction Steps

1. Make the bot connect to a voice channel
2. It doesn't work

Minimal Reproducible Code

@bot.slash_command(name="join", description="Tells the bot to join the voice channel.")
async def join(interaction: discord.Interaction) -> None:
    user = interaction.user
    await interaction.response.defer()
    if not user.voice:
        await interaction.followup.send(f"{user.name} is not connected to a voice channel.", ephemeral=True)
        return

    channel = user.voice.channel
    try:
         await channel.connect()
    except Exception as e:
         print(e)
    await interaction.followup.send(f"Connected to {channel.name}")

Expected Results

The bot connects to the voice channel

Actual Results

It connects, hangs there for some time then disconnects. Here is all that was outputted to the console:

Unclosed connection
client_connection: Connection<ConnectionKey(host='c-ams15-6ef27d2f.discord.media', port=443, is_ssl=True, ssl=True, proxy=None, proxy_auth=None, proxy_headers_hash=None)>

(that's it, there was nothing else)

Intents

default, voice states and message content

[Lulalaby]

We're pretty much aware of problems. Someone is researching more about voice and trying to fix stuff soon

idk i dont understand how this works but
pip install --upgrade git+https://github.com/Pycord-Development/pycord.git@2ae01b7

this fixed it idk why #2812 isnt just included when i do pip install py-cord or py-cord[voice]

[Lulalaby]

Because we haven't done a release for a long time lol
To get the current master changes you need to use the git dependency

[adrianfurgol]

Is there a plan when the fix is gonna be included in a stable release? I'm currently developing a musicbot implementation for my bot, but its impossible to ship like this as voice connection can just fail from one second to the next.

[Lulalaby]

Probably not in the near future cuz the voice topic is delicate

The 4006 fix is already available on py-cord 2.7.0rc1
