Voice channel join hangs at self.voiceclient = await command.author.voice.channel.connect()

[xhausted110]

After issuing a !join command, the bot hangs at self.voiceclient = await command.author.voice.channel.connect().
It successfully joins the voice channel, however, voice.channel.connect() doesn't return anything, thus causing the bot to hang at that point.

This appears to be a known issue with older versions of discord.py, as shown here: Rapptz/discord.py#2372

Updating to the latest version of the Discord.py fork causes other issues:
