but when i ran it on a device with Qt4.5 the program run very well.
what is the problem?

Uhm, Qt 4.5.3 is also Qt 4.5? Please elaborate on which versions you have exactly and what kind of errors, if any, you get.

i am working on version 4.5.3 the program run successfuly without errors but the sound does work.
but when i ran my application on a device having Qt4.5.0 the sound works fine.
