Play working on iPod, not on iPad

[grovecat]

I have created a stack with just one button and following script:

Code: Select all

on mouseUp
   iphonePickMedia "music"
   put the result into tSong
   play tSong
end mouseUp

On an iPod 4G running iOS 5.1.1 the above works perfectly. But on an iPad 3 also running iOS 5.1.1 it allows me to pick a song but it does not play. It is not a mute button problem, as I can play stuff otherwise.

I also tried putting a sound file into the engine folder and calling it directly. Again, works on the iPod, not on the iPad.

In all other respects the iPad is behaving normally, so I am puzzled by this problem.

Should I restore the iPad? A pain as I have a lot of apps on it, so any other ideas would be appreciated.

TIA
Don
