[Kind of picky...]
In the console, there's a checkbox with the clickable text "DSP." I know acronyms are normally capitalized, but in this case if the text read "dsp", the tk label/checkbox would accurately reflect the message one sends to pd to turn audio on and off (with the checkbox fulfilling the 0/1 argument).
I think someone complained recently that DSP would be less clear to a beginner than "compute audio." I think that's true, so if the beginner has to read a help file to figure out what it means, they might as well learn the message "dsp 0" and "dsp 1" at the same time (and be reminded of the _exact_ selector everytime they look at the console).
In a similar vein: what about "audiostatus" instead of "DIO"?
