Before you start playing a tone, you must:

  1. Construct a new instance of DevSound using the CMMFDevSound::NewL() function.

  2. Initialize DevSound using the CMMFDevSound::InitializeL() function.

    This function requires that you specify the DevSound observer class to handle callbacks. Once initialization has completed, successfully or otherwise, DevSound calls the MDevSoundObserver::InitializeComplete() function.

  3. Configure DevSound according to the tone you select to play.

    Note: The configuration differs according to the tone played.

The tone is a simple ring tone. You can play tones by calling the following functions:

  • CMMFDevSound::PlayToneL(TInt,const - TTimeIntervalMicroSeconds &) plays a single tone.

  • CMMFDevSound::PlayDualToneL(TInt,TInt,const - TTimeIntervalMicroSeconds &) plays a dual tone.

  • CMMFDevSound::PlayDTMFStringL(const TDesC &) plays a - DTMF (Dual and Multi-Frequency) tone.

  • CMMFDevSound::PlayToneSequenceL(const TDesC8 - &) plays a sequence of tones.
