Have barbershop songs on cd and Itunes that require listening to the left channel much more predominately to hear the baritone part. Am using Windows 8.1 on an HP 2010i desktop with a pair of Gateway speakers with woofer attached to the sound card that came with the desktop. The speakers have only one control of volume for both speakers. What need I do or must I buy something different to separately control the left and right speaker
