    Re: setting volume level in cmdaaudiotone utility

    Hi vijayannair,

    Well I am not sure about direct volumelevel to decibel conversion...
    Maybe one idea to start with is that you could find out the max volume per device, then divide that with the
    scale to get steps. Then you would start to know something about the specific device, because (if you did mean dBm)
    is hardware dependent...

    Maybe you could tell me more about what kind of use case you had in mind? To maybe display dB instead of volume
    scale or? About dB http://en.wikipedia.org/wiki/Decibel#Examples

    Best Regards,



    Code:
    axVolume()
    
    virtual TInt MaxVolume();
    Description
    
    Returns an integer representing the maximum volume.
    
    This is the maximum value which can be passed to CMdaAudioPlayerUtility::SetVolume(). This value is platform independent, but is always greater than or equal to one.
    Return value
    TInt 	
    
    The maximum volume setting.

    is raised when the audio player utility is not initialised.
