Python Discord Bot hosted on Heroku doesn't play audio

I'm building something like music bot and I decided to host it on heroku. Unfortunatelly it doesn't work properly. Everything works fine, bot connects to a voice channel, but I can't hear any audio playing from bot. Yesterday I got an error (logs from heroku):

2020-08-06T15:13:45.003027+00:00 app[worker.1]: Ignoring exception in on_ready
2020-08-06T15:13:45.004547+00:00 app[worker.1]: Traceback (most recent call last):

2020-08-06T15:13:45.004644+00:00 app[worker.1]:     raise OpusNotLoaded()
2020-08-06T15:13:45.004672+00:00 app[worker.1]: discord.opus.OpusNotLoaded

But today I somehow fixed it and I'm not getting any error messages, but audio is still not playing from bot. It looks like this:

2020-08-06T15:27:50.232782+00:00 app[worker.1]: [youtube] 1dOt_VcbgyA: Downloading webpage

After that it just stops. (When I run it on my computer everything works fine.)

That's how I solved it (when I tried to run it on my computer I got an error, but on Heroku it works perfect).

I added this to my script:

import ctypes
import ctypes.util
 
print("ctypes - Find opus:")
a = ctypes.util.find_library('opus')
print(a)
 
print("Discord - Load Opus:")
b = discord.opus.load_opus(a)
print(b)
 
print("Discord - Is loaded:")
c = discord.opus.is_loaded()
print(c)

Remember to put it before anything linked to audio (the best option is to paste it at the beginning).

"According to the discord.py docs you should not need it on a windows environnement, which is maybe why it worked on your local machine and not on heroku (which is unix based)."
