[82Y7, Realtek ALC287, Speaker, Internal] volume either 100% or off

[Erik van Tongeren]

The audio on my laptop, specifically when booting on ubuntu, is not working properly.
The volume slider either turns my audio off or it turns it up to 100%.
Anything else than muted is 100% on the volume slider.
