Question

I’m developing a web app for iOs device, but I have a problem with the html5 audio tag…
I designed a custom audio player, and I control the song with javascript functions.
With safari desktop the app works well, but on safari mobile it doesn’t recognize the duration of the audio; the value of the duration property is NaN.
I have to play, stop and replay the audio for retrieve the correct value.
Probably the cause is that the media preload is disabled on safari mobile…
Is there a way to read the correct value at the first shot?
