Well, it looks as if I can not have sound on iE.
My host does have m4a set up already so there is nothing they can do.
I just loaded my app on a Microsoft Surface and there was no sound.
On an Apply iPad, the UI only loads partially and there is no sound.
Maybe it's time to think about standalone versions.
On a side note. MS Surface surprised me by loading my flash based apps without a hiccup.
If that is the case, I might as well offer Flash and HTML5 versions for the time being.
What I found puzzeling was that Steve Jobs did away with Flash to tout HTML5 but .... anyway, not impressed.
If anyone has come across anything that would solve some of these issues, I'd love to hear about it.
