After I reinstaled Windows Vista Ultimate, my laptop doesn't play any music through additionally conected external ear-phones and external speakers system. It playes music only through internal laptop speakers and seems that it doesn't react that I put a music wire into laptop earphones or microphone hole. I thought it's wrong wires, but it works properly on my portable players or music centre, which is not a same as my laptop. Do I need some drivers or to do something else? It worked properly before reinstalling.
