Question : Problem: No audio after removing bluetooth headset

I was using a Motorola Bluetooth headset but decided not to use it anymore. I removed it from the bluetooth devices but I don't have any audio at all now.  I don't know where to check from here.  Any help would be greatly appreciated.  

I have a HP Pavilion dv9700 notebook with Vista Home Premium

Answer : Problem: No audio after removing bluetooth headset

restarting the computer automatically found new hardware and installed the sound card and therefore it worked.  Sorry if I wasn't clear.
