Based off of my RE of 12.0.2 audio services, the newly added parameter can be safely ignored due to ryu not using fixed-size I/O buffers.
I happened to notice this when checking Ryu's IPC structures. After double checking with RE it seems the current check is incorrect so use the correct member to fix that.
This was tested against HW with https://github.com/Xpl0itR/Input-Test/tree/master/Input-Test and a few changes to record the minimum value axis value when the stick buttons were marked as pressed.
