I have a 2.1 speaker system for my PC. Should I max the hardware volume and adjust the volume using software or max the software volume and adjust the volume using hardware? I think I read somewhere that is uses less power to max the software volume and adjust the hardware volume. So, having the software volume at 100% and the hardware volume at 50% will use less power than having the hardware volume at 100% and the software volume at 50%. Is that true?
