I tested it myself and it worked fine with DS3.
Code: Select all
#button, volume, pushtime
VOLDOWN, 0, 0.5
VOLUP+HOME, 30, 1
The last value, pushtime, is the time you have to hold the button combination for the plugin to work. 0 will be instant. The middle value ranges from 0 to 30 and is the volume the combo will set.
If you want to access the volume buttons from DS3 macrofire plugin would be a better option, since I think it allows to remap buttons, so you could set something like "LTrigger+Select+UP" to the volume up key, for example.
EDIT: I tried macrofire and sadly it doesn't seem to work with DS3 wven though you can configure the remaps with DS3. Too bad, this would have also worked to toolge the tv output. But this also means that macrofire recognizes the ps3 buttons in a different way than the real ones, so maybe this means that modifiying macrofire to work with DS is possible, maybe even mapping buttons to the second analog stick and triggers, but that is certainly beyond my limited programming skills.
