I have BT5R2 and installed it on my sony vaio laptop. When ever i hit the key to ajust the screen brightness or ajust the volume it show that it is ajusting BUT it doesnt ajust. The screen stay the same brightness so does the volume.

Oh and how do you use Kmix?
I click on the icon in the menu and all it does is loading, loading and then nothing...
I also can play MP3 or MP4...
