laptop speakers not working

[Understudy]

  Hi,

I have an aspire one 532h. The speakers on the netbook do not seem to 
produce sound. However if I use the headphones I can hear the sounds 
just fine.

I am running pc-bsd 8.0

So my question is what can I do to get sound from the speakers built 
into the laptop?
