I'm trying to use OBS to sing over an audio track. The audio track is set to go live as soon as the scene is activated. The audio source has the monitor and broadcast audio on so that I can hear them in the headphones and sing on the beat of the music. Since there is a delay between the mic and the music, I have to add a 150ms delay in the music track. This works precisely once. If I switch away from the scene and back to it to restart the track, the audio goes 150ms out of whack, and another 150ms every time I do this. The only way to get the mic to sync with the audio on the recording is to restart OBS every time. Can someone assist?
