我的 discord bot 不播放 mp3 文件并且没有给出任何错误

My discord bot doesn't play mp3 file and it gives no errors

我试过调试,但一切正常,然后什么也没有发生

澄清一下filename是包含文件

的文件路径
async def playing_video(ctx, filename):
    global vc
    voice_channel = ctx.author.voice.channel
    channel = None

    # Check if user is in a voice channel
    if voice_channel != None:
        channel=voice_channel.name
        print(f"Voice Channel: {voice_channel}")
        vc = await voice_channel.connect()

       # It reaches here with the right path to the file and what looks like the right vc but then nothing happens.

        vc.play(discord.FFmpegPCMAudio(filename), after=lambda e: print('done', e))
    else:
        await ctx.send("You must use *join first!")

我只找到一个和我有同样问题的人,但他只是写了“我解决了”,没有说如何。

我觉得自己像个白痴。问题是机器人没有发言权。

我将此搁置,因为我相信有人会这样做。
