Hello, I have a minipc with an AMD 5800H. I noticed that mpv was not using hardware decoding for some reason, and when I ran nvtop (which I specifically remember working before), it said "No gpu to monitor".
It was working before and nothing has been touched, maybe an update broke it. Though everything still looks fine on my 4k screen (somehow?).
I did some searching but couldn't really find anything. Any ideas on how to fix this?
System info
Zorinos 17
I am using HDMI. Happens on x11 and wayland
