[solved] Phonon::createPath problem on windows

Hello. I wrote application to listen internet radio. All works fine on linux but i have problem with windows. On windows with sdk application it works but when i try to run my application on windows without QT sdk i have error.
I have problem after this line

Code:

path=Phono::createPath(mediaObject,audioOutput);

I check if this path is valid and i get false.

Do you have idea where is problem?

This is all code to phonon on:

Code:

mediaObject = new Phonon::MediaObject(this);
    audioOutput = new Phonon::AudioOutput(Phonon::MusicCategory, this);
 
    if(mediaObject==NULL||mediaObject->errorType()!=0||audioOutput==NULL)
    {
        if(mediaObject!=NULL)
            QMessageBox::critical(this,tr("Error!"),tr("Nie moÅ¼na uruchomiÄ‡ serwera dÅºwiÄ™ku.\nByÄ‡ moÅ¼e jest zjÄ™ty przez inny program.")+
                              tr("\nAplikacja zostanie zamkniÄ™ta."+mediaObject->errorType())
                              ,QMessageBox::Ok);
        else
            QMessageBox::critical(this,tr("BÅ‚Ä…d!"),tr("Nie moÅ¼na uruchomiÄ‡ serwera dÅºwiÄ™ku.\nByÄ‡ moÅ¼e jest zjÄ™ty przez inny program.")+
                              tr("\nAplikacja zostanie zamkniÄ™ta.")
                              ,QMessageBox::Ok);
        exit(-1);
    }
 
    path = Phonon::createPath(mediaObject, audioOutput);
 
################
I get error here
################
    while(!path.isValid())
    {
        if(QMessageBox::Ok==QMessageBox::critical(this,tr("Error!"),tr("Path is not vaild.\nAplikacja zostanie zamkniÄ™ta."),QMessageBox::Ok|QMessageBox::Retry))
            exit(-1);
        else
            path.reconnect(mediaObject,audioOutput);
    }

I add this dll files to application folder:
- libgcc_s_dw2-1.dll
- mingwm10.dll
- phonon.dll
- phonon4.dll
- QtCore4.dll
- QtGui4.dll
- QtNetwork.dll

Edit:
Always when i create topic I find solution. So the solution is to create phonon_backend folder and put there dll phono files :) That`s all. So sorry for create topic and for my english
