Do you know whether it is possible to adjust the sound volume from within an application on 7650? CMdaAudioPlayerUtility API should support volume control, but calling SetVolume() seems to have no effect. Codes are the followings

//Create a sample player and load a sample from a file

CMdaAudioPlayerUtility* sampleplayer =
CMdaAudioPlayerUtility:: NewFilePlayerL(KSampleFilename, *this);

// Change the volume

sampleplayer->SetVolume(volume_value);

//Play the sample
sampleplayer->Play();

What problem is it? Your help would be greatly appreciated !
