do you have “ogg” multimedia codec installed on your windows?

Do you expect mediaObject to live long enough this way to actually do anything? You create the player, and then immediately destroy it again. I would not expect that to work…

Yes I have ogg, and I tested with .wav and dont work.
Andre, This is just a simplified test case, in my real code delete is not so close from createplayer().

Sorry, hard to judge your real problem without seeing your real code.

I discovered why isnt working, Im using .qrc file to store my audio files and playing by it like this

In linux it work, in windows it only work if I set the MediaSource like this

this dont need to be reported as a bug? since it work in on way on windows and another in linux?

You could report it, yes. That might be a good idea.
It is a weird issue. The latter version should not use the resource at all.

This is a pity, I liked the way qt make sounds builtin the app

it should be fixed. not good idea on using #ifdef OS for a syntax like this!
