Not sure I see the point, could you please elaborate on what you are trying to achieve here?
Setting Drivers="" in the config file is supposed to prevent sound from being used at all - there are actually howtos and such on the net that say this and it's sometimes given as tech support advice, so I assumed it worked. But, it doesn't seem to - Drivers="" always causes wineoss.drv to be loaded instead. So this patch lets you to make the app think there are no sound cards in the machine.
