Can't get audio and touchpad working (HP 11 G4/KIP)

HI! I recently got my hands on a really old chromebook (HP Chromebook 11 G4/KIP) and I succesfully installed Windows 10 with 0 issues! However, despite following the ‘‘Coolstar’s Windows Install Helper’’ and installing all the listed drivers for my specific device I haven’t been able to get both the audio and touchpad working. Am I missing something? I read all guides from start to finish but I’d like to be pointed out if I made any mistake. Thanks for reading this c:!
