【中文标题】Discord.py music_cog，机器人加入频道但不播放声音

【英文标题】：Discord.py music_cog, bot joins channel but plays no sound

【问题描述】：

我大约一周前开始使用python。我已经在 YT 上观看了所有相关视频并检查了谷歌页面等。但仍然没有运气。我的机器人完美地加入了语音通道，当我使用播放时，它会下载并可能会启动播放功能，但没有声音或任何东西，它只是加入并等待 1-2 分钟然后离开并出现超时错误。

        voice_channel = ctx.author.voice
        if voice_channel is None:
            # you need to be connected so that the bot knows where to go
            await ctx.send("Connect to a voice channel!")
        else:
            song = self.search_yt(query)
            if type(song) == type(True):
                await ctx.send(
                    "Could not download the song. Incorrect format try another keyword. This could be due to playlist or a livestream format.")
            else:

            # try to play next in the queue if it exists
            await self.play_music()
            await ctx.send("Skipped!")


def setup(bot):
    bot.add_cog(music_cog(bot))

我确实启用了日志，当它连接时只有那个信息：

INFO:discord.voice_client:Connecting to voice... | INFO:discord.voice_client:Starting voice handshake... (connection attempt 1)

我还检查了 FFMPEG 及其路径，尝试了不同的代码和方法，但即使它们有效，也没有声音。我也安装了 discord.py[voice]。

感谢您的帮助，谢谢。

【参考方案1】：

我在 19 小时后发现了它的意图

intents = discord.Intents(messages=True, guilds=True, reactions=True, members=True, presences=True)

阻止机器人连接到 voice_channel 服务器，即使它看起来像是在语音通道中。

删除它解决了我的问题。
