i am using unity 2019.4, i have no audio at all, i built a different game in 2020.1 and had full sound, just opend the 2020 game and have no sound on that now as well. as anyone else had any issues with audio.i have built a test vercio in 2020 and 2019.4 and if i click the sound it plays but not on play or through the code.
If you are able to hear the audio in your build but not in the editor, it might be that the sound in Unity is muted. Click on the Mute button in the game window.
If that’s not your problem, are there any error messages in your console?
