Built-in webcam Asus UX32A not working

I got a problem with my built-in webcamera on Asus Zenbook UX32A. It seem no longer responding. I've tried to uninstall/install the driver through lifeframe software as the asus costumer service suggested. Then tried to turn it on via alt+v but the lifeframe couldn't find the camera. "The device not found"

I've been looking for the answer almost a month on the internet but nothing works. Is it a hardware failure? how can I check it if it's a hardware failure?

Please help.

Thanks

*The device manager page isn't showing anything suspicious. No yellow marks. Every driver have installed.
