Thank you for your replay. I have found the path of the executable to be: ”/usr/local/bin/” but there is no “ballhit.wav” in that dir. I can go to that dir and do ./app and it runs like normal, but the sounds does not work. I did a “find . -name “ballhit.wav”” with root and found nothing on the phone. So, the file has not been copied ? How can I ensure the file is copied and installed with the executable? I think that is my problem.. I need to copy the file over to the phone when i run it from Qt Creator. I have done the following in an attempt to fix it: In the same folder as src.pro i got ballhit.wav, and in src.pro i added this: OTHER_FILES += ballhit.wav target.path = $$DESTDIR target.files += ballhit.wav INSTALLS += target I have also added a build step: “make install”
