Doesn't work in Webkit browsers

I'm using MP3 Player on my sites and it works fine in IE and FF, but it shows "You may need: Adobe Flash Player" on Safari and Chrome, and other Webkit-based browsers such as the one on Android phones. I have Flash installed for Safari and Chrome, as well as my HTC EVO 4G, so it's not that it's actually missing Flash. Can anyone else verify this? Seems like a pretty major issue but I couldn't find anyone else mentioning it so maybe it's just me? Hope to hear back from you guys. Thanks!
