• Heroku Python Discord music bot no sound [closed]

  15 septembre 2022, par olfis

  I just created python discord bot using youtube_dl and discord.py
I wanted to keep it live 24/7 on Heroku but there is one issue...
My bot is working good on my PC, but when I run it from Heroku bot just joins voice channel, adds songs to queue but I can't hear anything, his audio it's always off...

  


  Here's a screenshot of installe buildpacks on heroku.
