I had to install the linux LTS kernel and used that instead.
My laptop is the Lenovo Ideapad Flex 5 14IAU7
It doesn’t work in the regular arch kernel either (tested on 6.16.1-arch1-1)

Hi, is the issue resolved? same issue happened with my laptop on 6.17.7 kernel, had to switch to LTS kernel.

It’s working for me now.

So an update to the kernel fixed it?
