Using Sound with Symbian

hi author

i have just started working on symbian. I am writing program using CMDAAUDIOOUTPUTSTREAM utility. I receive a song ( in .au format) from remote machine as a RTP packet over UDP. Since there are no RTP APIs provided in series 60, i receive udp packet on my machine, remove the headers and stream the packet using CMDAAUDIOOUTPUTSTREAM utility.But i only listen noise but not the song. I also tried by converting packet in .au format into raw PCM16 using CMdaAudioConvertUtility bt am still not able to play the song. When i tried the second option my program leaves in OpenL()

I am in great trouble. Please help

I m including some portion of my code here ---

void CSocketsReader::GetFrame() iFramePtr.Set( iBuffer.MidTPtr(12)); isrcdesc = new(ELeave) TMdaDesClipLocation(iFramePtr); TMdaClipFormat* iCodecSrc = new(ELeave) TMdaAuClipFormat(); TMdaClipFormat* iCodecDest = new(ELeave) TMdaRawAudioClipFormat(); TRAPD(error, iAudioConvertUtility->OpenL(isrcdesc, idesdesc, iCodecSrc, iCodecDest)); if(error) CEikonEnv::InfoWinL (_L("Error"),_L(""));

void CSocketsReader::MaoscOpenComplete(TInt aError) if ( aError==KErrNone ) GetFrame();

else CEikonEnv::InfoWinL (_L("Open Failed"),_L(""));

void CSocketsReader::MoscoStateChangeEvent(CBase *aObject, TInt aPreviousState, TInt aCurrentState, TInt aErrorCode)

if (aCurrentState == CMdaAudioConvertUtility::EOpen) iAudioConvertUtility->ConvertL(); if (aCurrentState == CMdaAudioConvertUtility::ERecording) TRAPD(error3, iOutputStream->WriteL( *(idesdesc->iDes))); delete isrcdesc; return;
