Using QSound::play("...") not working

[Charvi]

okay I used a workaround due to lack of time to experiment. I used the system command from within Qt and used aplay utility.

Now I get a key press sound on every keypress which I have handled in the event filter; because there I use the system command. But what should I do for the keys which are not handled by the event filter and which are internally handled by Qt. Like I have used a QScrollArea. The scroll bar navigation takes place with the up and down arrow keys. This is internally handled by Qt and hence no sound is played here. Is there anyway I can play sound here also? Ofcourse there is a way. Can anybody point out please.

Please reply.
