No audio after effects cs6

Hi,

I use an HP Probook and After Effects CS6. I tried to put some audio into the program and previewed it, but it doesn't play anything. The playhead moves just fine and AE even acknowledges there's sound there (waveform). It just won't play anything. Sound is enabled in the timeline and my own speakers aren't broken. 

I don't know my specs and I don't know how to find them, so if you want me to give you specs, just ask, but you have to tell me how to find them.

Thanks.
