This is now more about maintaining good all round interactivity and fairness. Improving audio beyond ordinary scheduling tweaks is another issue which may lead to some form of soft user RR task. su tasks already can be reniced or made RR to help. > interactive processing in the desired time.

However neither Ingo nor I (and all the other contributors) are trying to make an audio app scheduler. At some stage a modification will be made to the mainline kernel which will have adequate audio performance in many (but not all) settings, and more importantly be fair and interactive. Con
