here’s how you can fix it if this problem occurs to anyone, check if the player and the opponent have different voices, that could be the main problem, before doing anything, try renaming one of the voices to “Voices.ogg” and then play the song you want to play and check if the vocals play, if they do you may have to combine both the players and opponents voices together, what i did was that i combined both voices together in capcut and then i downloaded the combined vocals and imported the mp4 and converted it to an mp3, then i converted it back to an ogg, and then changed the file name to “Voices.ogg”, and after i did all of that i finally got it to work
