Glad to help and glad it worked!
The sync was off when I did Cardio Kickboxing and Cardio Barre yesterday. It bothered me some until I stopped watching the video and just went by verbal cues and the music beat.
Hi - I'm having the same "no volume" problem with Cathe Live in my iPad, but my iPad is much older (iPad 4) and I don't have that mute button. I am able to play Cathe Live video through a web browser on my iPad.
