To do this you have to dissable the sound card in BIOS
--How to enter in BIOS configuration?
1. well, wen the pc is starting (before u can see the desktop), it will show u some options, in my case is the button F2..
2. when u are in BIOS configuration, go to "Advanced"
3. then go to "peripheral" an disable "sound"
4. Press F10 and select "yes" to save that configuration and let the pc Boot normally. (now you will not hear ANYTHING from programs, aplications and other..)

-Now, simply play APB and tell me if it freezed or not
