Regression: Phonon fails to play mp3 on latest N8 FW

Summary: When attempting to play an mp3 file through Phonon on the N8, no audio can be heard.

Same application with same audio files has been working in earlier FW versions on the N8. App tested on the N97 mini works fine. So I assume some regression in new/current FW releases of the N8.

Attached PhononMp3.zip: a small sample app to reproduce. It plays an mp3 file that is assumed to be in E:\music.mp3
Attached PhononMp3OnN8.log: output log from app on the N8. Status says that mp3 is playing, but no audio can be heard. Manually setting the volume to 1.0 / 100.0 / 255.0 / 9999.0 doesn't change anything *.

It's also possible to reproduce with the Phonon music player example that comes with the Nokia Qt SDK (C:\NokiaQtSDK\Examples\4.6\phonon\qmusicplayer)
Playing an mp3 works on the N97 mini, crashes on the N8 with: "Process 724, thread 729 stopped at 0x7ce8b5e0: A data abort exception has occurred."

• On a sidenote: the Phonon documentation should contain more info about setting the volume through Phonon::AudioOutput->setVolume(). There is no method to query the value for the maximum volume (is it 1.0?), and no further information about this is given in the documentation.
