Now i want to change GSM volume during a GSM call, and try to use the way of changing registry during a call.
Now i am confused by several items in registry.
there is several items in /HKCU/controlpanel/volume, include: screen, key, ringer, volume, mute
I had set the "ringer" and "volume" to different value, its write and read are all seems ok. but it is not influence the volume during a call.
I am consufed by its meaning.
Who know that?
