I have added this in .pro file:

Code:
symbian {
    TARGET.UID3 = 0xA000E3F5
    include($$PWD/../../symbianpkgrules.pri)
soundFiles.sources = data\*.wav
DEPLOYMENT += soundFiles
}
And then in main.cpp:

Code:
QSound::play("somesound.wav");
And when I start it, no errors but I only hear Windows "error sound".

What is wrong with this? I know that sounds won't work in resources.
