Hello, I have the Dell Latitude 5430 Chromebook 2-in-1 (brya, crota360) running mrchromebox full UEFI firmware version 2509.3, Windows 11 IoT Enterprise LTSC 2024.
Obviously the side power button works, but my side volume buttons do not seem to work in both tablet mode or clamshell mode. I can verify the side volume buttons were working in chrome OS on the stock google firmware before the full UEFI rom flash.
Does the mrchromebox firmware support volume buttons in Windows? How can I get my side volume buttons working?
the short answer is that the side volume buttons use the same keyboard scancodes as the home row ones, so like the home row buttons, they require left-CTRL to be pressed to activate the non-F-key function. Not sure if this is configurable via coolstar’s driver or not
Doesn’t seem to work, regardless of left control being held or not. I also tried using PowerToys like @Taz recommended, though that didn’t work either as it seems the system doesn’t recognize the side volume buttons whatsoever.
I can verify the ribbon cable is connected to the zif connector properly and firmly, the tab is locked and on the black line on the cable, and works as intended on chrome OS.
