Abstract:
1. A control device comprising: a storage device for storing an audio-output matrix having a plurality of matrix elements, each matrix element associated with a pair of audio sources from a plurality of different audio sources, including at least first, second and third matrix elements, wherein the first matrix element indicates if a first audio source can interrupt a second audio source, the second matrix element indicates if the second audio source can interrupt a third audio source, and the third matrix element indicates if the third audio source can interrupt the first audio source; and an arrangement for outputting a selected one of the plurality of audio sources to a common output device, wherein the control device is configured to manage audio output interruption requests from the plurality of different audio sources as a function of the matrix elements of the audio-output matrix, wherein the managing includes a non-linear mode in which, if indicated by the matrix elements, the first audio source can interrupt the second audio source, the second audio source can interrupt the third audio source, and the third audio source can interrupt the first audio source.
