Setting process priority in Qt symbian

[cnavarro]

Hi

I´m doing an application that plays audio streams using qt-mobility 1.2. Playback is fine but when I switch the application to the background and start using other applications, it starts to have small audio freezes. First I thought it was related to network connection, but it happens even when the audio is buffered, so I´m now thinking more in CPU workload issues.
Is there a way to ensure that my app has higher priority? Can I do something like this in Qt or I have to use native symbian?

Best regardsand thank you in advance
