Abstract: Methods, computer program products, and electronic devices are provided for managing sound in a plurality of computer-executed applications. One method includes: operating a sound manager function to provide a user with an option to selectively mute up to n-1 applications of n applications, where n>1; and in response to the user choosing to selectively mute up to n-1 applications, the sound manager function selectively muting the up to n-1 applications. Another method includes providing a user with an option to selectively mute up to n-1 applications of n applications, where n>1. In response to the user choosing to selectively mute up to n-1 applications, at least one action is performed in response to requests to play sounds by the selectively muted applications so that the sounds are muted with respect to a sound device.

Abstract: The invention concerns methods and apparatus for generating and controlling a slider control for simultaneously changing values of two variables. In the methods and apparatus of the invention a graph having two axes is displayed, wherein the axes correspond to first and second variables. The values of the first and second variables may be simultaneously adjusted using a slider control displayed in a two-dimensional region between the axes. As a user adjusts the slider control and changes values associated with the two variables, the methods of the present invention calculate the effects of the adjustment on a value of a third variable. A graphical component is then used to depict the updated value of the third variable. Additionally, curves corresponding to constant values, or ranges of values, of the third variable are displayed in the two-dimensional region to assist a user in selecting values for the first and second variables.
