Debugging jPlayer issue for iphone and ipad..

We have an audio player we use on the our website is "jPlayer". The player is wrapped in my own code using "KnockoutJS" which is what controls the player on the page. The player works on all desktop browsers (including Safari on Mac OSX) and on Android, but NOT on iPad and iPhone appear to be broken. We need someone to debug the issue and fix. Not sure how big or small this job is, as could be something simple.
