1. A sound volume adjustment system for a personal computer, said personal computer having a sound device, the system comprising:
- a memory resident on the personal computer in which a plurality of sound volume adjustment coefficients are stored, each of the plurality of sound volume adjustment coefficients corresponding to a respective one of a plurality of software applications;
an operating system resident on the personal computer; and
sound volume adjustment control means resident on the personal computer for adjusting, based on said plurality of sound volume adjustment coefficients, sound volume data for each application of the plurality of software applications, and for transferring the adjusted sound volume data to the operating system,wherein said sound volume adjustment control means adjusts said sound volume data for each application of the plurality of software applications by multiplying said sound volume data for each application by a corresponding one of said plurality of sound volume adjustment coefficients; and
wherein each of the plurality of sound volume adjustment coefficients are set as multiples of a variable level of a sound volume of a system sound generated by said operating system, said variable level of said sound volume of said system sound being unchanged when an application of the plurality of software applications requests the operating system to open the sound device.
