Thanks for providing such a conspicuous example.

Can I turn the keypad beeps off, whenevr i want. Whenever a user will press a key (lets menu Key), there should be no beep in response to that.

Is it possible without switching to Silent mode.

Hi Zeep, I am currently using this audio player to SetRepeats to my sound file. But I need to implement 2 sounds looping one after another. Is that any methods that can allow me to do so?

to 1) Of course, this helps understanding the states of the utility. But during my tests, this states get a little bit "messed up" (my fault). Thats the problem with your own states.

to 2) It's the following tone. Try this:

  Install the "sound" example out of the series60Ex folder and start it on the phone (not the emulator)
  Check, if the Utility "Tone" is selected
  Play the tone (very ugly sound by the way)
  Stop the Playing, before the tone runs out by selecting "stop" from the context menu
  Play the tone again, this time in its whole length
  Try to play it again, but this time the context menu still shows you "stop"/"exit"

Bingo. This is the bug. Now you can select "stop" (that calls cancelPlay) and go on playing. But thats still a bug.

Its impossible to loop a sound (for example an alarm) and stop it immediatly (the user reacts to the alarm) and start it later again with the same ToneObject. You have to create a new ToneObject every time you cancel the Playing.

I've posted this in the nokia-forum and in the newsgroup (i've copied the way to reproduce this bug from my news entry, by the way). No response so far...

In order: 1. You're right, in a real-world program it generally would be better to use State(). However, I'm hoping that my (bad) use of iFreeToPlay and iFreeToPrepare will have served as a guide to understanding the state-based system.

2. Interesting. The docs do note that MatoPlayComplete isn't called for the tone that's been cancelled - are _all_ subsequent tones defective, or just the one immediately following it? Do Nokia know about it?

Thanks for that example, it helps me understanding the tone utility.

But you can improve (or correct) this example:

1. Why didn't you use the Status function of the ToneObject ? You don't need the iFreeToPlay and iFreeToPrepare members to check the state.

2. I've found a bug in that utility:After you called the cancelPlay function for one tone, the next tone you play never evokes the MatoPlayComplete function. Try this, with the sound example in the series60ex folder. Maybe this only happens to 7650s. I don't know.

You have to recreate the UtilityObject after called the cancelPlay function. Add this in StopL an it works fine:

// reset the tone utility by recreating it

delete iMdaAudioToneUtility; iMdaAudioToneUtility = CMdaAudioToneUtility::NewL(*this); iMdaAudioToneUtility->PrepareToPlayTone(iFrequency, TTimeIntervalMicroSeconds(iDuration));

i have tried the code by implementing example code from the SDK. i have succeded testing in emulator. but when I put it in the real device, i received system error. why is that? For your information, I implement the player not the tone player. by the way, friend of mine has tried the code to play midi file. it couldnt play in emulator, but worked in sony ericson P800 (UIQ SDK) device. Can I do the samething with Nokia 7650 (Symbian 60 SDK) device?
