Question

I have an issue on an iPhone app.
I am looking at SystemVolumeDidChangeNotification and the related documentation and also browsing the net.
But I can’t find a simple way to get the current value of the SystemVolume.
I cannot believe this information is impossible to get simply, but for some reason I have not been successful.

I also noticed the music application on iPod touch, does exactly what I would like to have, so it must be easy.

Anyone knows the answer?

Thank you for any relevant information.

Here is the code for getting the current volume, the result output will be from 0.0 to 1.0.

Float32 volume;
UInt32 dataSize = sizeof(Float32);

Float32 currentVolume= AudioSessionGetProperty (
                         'chov',
                         &dataSize,
                         &volume
                         );
