C2422HE, sound issues and firmware version
I've just got a C2422HE. Initially the speakers work, but now they don't and the volume down white LED is stuck on.
I'm using a Dell laptop via USB-C. Camera and Mic work.
It's on firmware M2T111.
I've found firmware M2T105, but isn't that older?
Any help appreciated

Thanks for pointing me to the firmware.
The touch button for Vol down was stuck "down" and not allowing the volume to be increased. (hence no sound)
