如何让我的 discord.py bot 在语音通道中播放 mp3？

Question

我是 Python 的初学者，我最近开始为一些朋友和我制作一个不和谐的机器人。这个想法是输入 !startq 并让机器人加入频道，播放本地存储在同一文件夹中的 mp3 文件bot.py 也在。

import discord, chalk
from discord.ext import commands
import time
import asyncio

bot = commands.Bot(command_prefix = "!")

@bot.event
async def on_ready():
    print("Bot is ready!")

@bot.command()
async def q5(ctx):
    await ctx.send("@here QUEUE STARTING IN 5 MINUTES")

@bot.command()
async def q3(ctx):
    await ctx.send("@here QUEUE STARTING IN 3 MINUTES")

@bot.command()
async def q1(ctx):
    await ctx.send("@here QUEUE STARTING IN 1 MINUTES")

@bot.command()
async def ping(ctx):
    ping_ = bot.latency
    ping =  round(ping_ * 1000)
    await ctx.send(f"my ping is {ping}ms")

@bot.command()
async def startq(ctx):
    voicechannel = discord.utils.get(ctx.guild.channels, name='queue')
    vc = await voicechannel.connect()
    vc.play(discord.FFmpegPCMAudio("countdown.mp3"), after=lambda e: print('done', e))
    bot.run('TOKEN')

到目前为止，我的机器人很好地加入了频道，但实际上并没有播放 mp3。我在“非官方 Discord API Discord”和其他一些编程 Discord 中问过无数人，但我还没有得到答案。

我对我的不和谐机器人做了类似的事情，这里有一些您可以参考的示例代码。如果您正在播放 mp3 文件，请确保安装 ffmpeg，我在设置机器人时按照此处的说明进行操作https://github.com/adaptlearning/adapt_authoring/wiki/Installing-FFmpeg

@client.command(
    name='vuvuzela',
    description='Plays an awful vuvuzela in the voice channel',
    pass_context=True,
)
async def vuvuzela(context):
    # grab the user who sent the command
    user=context.message.author
    voice_channel=user.voice.voice_channel
    channel=None
    # only play music if user is in a voice channel
    if voice_channel!= None:
        # grab user's voice channel
        channel=voice_channel.name
        await client.say('User is in channel: '+ channel)
        # create StreamPlayer
        vc= await client.join_voice_channel(voice_channel)
        player = vc.create_ffmpeg_player('vuvuzela.mp3', after=lambda: print('done'))
        player.start()
        while not player.is_done():
            await asyncio.sleep(1)
        # disconnect after the player has finished
        player.stop()
        await vc.disconnect()
    else:
        await client.say('User is not in a channel.')
