the problem is using the hardware shortcut for sound control(weel up/weel down)
when the program is turned on can only control the volume of the program, the volume of the other windows programs do not change. The sound of the program is not synchronized with the windows.
example: I have windows dispensing 50% for sound devices, the volume of the winyl ranges from 0% to 100%, of those 50% defined windows. other programs simultaneously connected dont change volume. If I try to mute the sound, I can only shut down the program, other programs remain whit sound.
windows 7 x86 sp1, build 7601.
I hope I have been fully understood, sry my rusty english
