I have been working on my first movie in Movie Studio 2023. I was using the 2nd track for music. I started adding videos into the movie, and I was cutting the music at the point that the still photos transitioned to video so that I could lower the volume of the music while the video plays. Everything was working great, and then all of the sudden, the music did not play. I can still hear the sound from the video but not the music. I can't even hear the music when it's playing during still photos. I tried deleting the song and dragging it in again. Still nothing. I tried dragging in a different song. Still nothing. The "Mute Audio" is not on, so it's not that. I feel like I must have turned off the audio somehow, but I can still hear the sounds from the videos..... Help please....
