Thank you for responding but I don't want to mute the video clip. I want to hear only the video clip when it's playing. I want to mute the background audio during the video clip. Right now I hear both the background audio (music) and the sound from the video clip. I have tried unlinking the sound clip from the video clip, then I right clicked the unlinked audio clip, and checked the option to "Suppress the volume of soundtrack behind this video clip". But that didn't do anything. I can still hear both the background music and the sound from the video clip at the same time when playing the slideshow. Help.
