The play message went well, but the song is not playing.

There was no error in the terminal.

Please don't leak your token. I invalidated it for you to prevent abuse.

[Seunghan-Jung]

Oh, thank you!

[SSnowy9]

Doesn't work for me either, I have searched everywhere and still searching. If there's a fix let me know!

[syricium]

Yes, it doesn't send any errors to the console, as you've silenced the console. You probably don't have discord.py[voice] or PyNaCl installed

[SSnowy9]

I figured out that I had intents and it was blocking bot from fully connect to voice channel, removing it enabled bot to Play anything.
