I am using windows 7. I took the speakers to the service center. The service person speakers to his system, there all were playing. He showed me some volume control options. He has windows xp. The volume options are different from my volume options.
When asked for your hardware config you need to provide model of motherboard, model of video card, model of sound card, brand and specs of ram, version of Windows 7 etc. Also helpful is if the system is prebuilt or home built.
