How to increase volume of application sound on pocket pc
Q:
My application plays different sounds in different conditions..all working fine. Only trouble is when incoming call alert is there , sound produced by device (RINGTONE) is loud but sound played by application (parallely to Ringtone) is very low. Does ringtone have a higher priority for the device speaker than our application sound.
A:
Yes in effect the ringtone sound has a higher gain setting than your application audio when an incoming phone call is detected. This is implemented by the concept of "classes".
Further details including details of how you can alter this behaviour can be found in the Windows CE Multimedia Team Blog in an article titled "The WaveDev2 GainClass Implementation" available at
