CMdaAudioPlayerUtility panic 1 on P800??

Hi

I am playing sound using a wav file as described in the NEWLC article ttp://www.newlc.com/article.php3?id_article=38.I am successful in playing sound in N9300.But it is not working in case of P800 ,my application crashes giving 1 PANIC. Given that 1 panic is raised by the function play()/SetVolume() in the CMdaAudioPlayerUtility class when if the audio player utility is not initialised.But I did initialise it properly and is working fine in N9300 .

For N9300 i used the filepathname as "Z:\\system\\ringing_tones\\attraction.mid" where the inbult ringtones r stored for N9300 and its working fine there.
For P800, used the DeafultSounds folder on the device "c:\system\data\DefaultSounds\alarm.wav".I tried using mid file also.Nothing works..What might be the problem ...... Below is the code snippet for the same...



in OkToExitL() fn


case EDynamicPrefPlay:
      {
      
         if((iPlayCtrl->State()) == CEikCheckBox::EClear)
             {
                   
            
            //TFileName iRingTone=_L("c:\\documents\\Media files\\audio\\unfiled\\canyon.mid");
            TFileName iRingTone=_L("c:\\system\\data\\DefaultSounds\\alarm.wav");
            
            User::InfoPrint(iRingTone);

            if(iAppUi.iPlayerAdapter)
            {delete iAppUi.iPlayerAdapter;iAppUi.iPlayerAdapter =NULL;}
            
                //iAppUi.IsAudioAlarmActiveFlag=EFalse;
                User::InfoPrint(_L("Play0"));
            iAppUi.iPlayerAdapter   = CPlayerAdapter::NewL(iRingTone,iAppUi);
            User::InfoPrint(_L("Play01"));
                   
                iAppUi.iAudioAdapter= iAppUi.iPlayerAdapter;
                 iAppUi.IsAudioAlarmActiveFlag=ETrue;
                 User::InfoPrint(_L("Play002"));
                
                iAppUi.iAudioAdapter->SetVolume(iAppUi.iAudioAdapter->MaxVolume());
                User::InfoPrint(_L("Play0003"));
                   iAppUi.iAudioAdapter->PlayL();
                   User::InfoPrint(_L("Play00004"));
            
            
            }
         
         break;
