I just bought a HP Pavillion p6204y running Windows 7. I am unable to get sound from my external speakers. The only sound is coming from the internal (monitor) speakers. The external speakers are plugged into the correct analog jack in the rear of the tower, and Realtek shows this, but I only get sound from the moniotr. How can I reverse that and get sound only through the external speakers? I am unable to easily determine how this can be done through either the Realtek Audio Manager or through the Sound settings in the Control Pannel. Help please!
