[PATCH v3 0/1] MR338: mmdevapi: Override product strings for DualSense controller audio devices

[Claire (＠ClearlyClaire)]

Some games expect the DualSense audio device (used for haptic feedback and controller speaker) to be called “Wireless Controller”.

This is the case of Final Fantasy XIV Online and Final Fantasy VII Remake Intergrade, and possibly other games as well. Together with !337, this is enough for all DualSense features to properly work with those games (provided the controller is plugged in before the game is started).

Note that this is not sufficient for many other games which have more elaborate logic for finding the DualSense audio output.
