Big Box + Dolphin + Wii Remote = Pain

I hope removing admin privileges solved the issue. I have the same setup except Xbox 360 instead of DS4. If you have an Nvidia card you might give moonlight a try. You can install it onto the steam link via USB. Big box streams a lot better through it.

I had the same problem and the post from Tatts4Life is what fixed it for me.

In Dolphin, I checked the "Continuous Scanning" option under controller settings and now when I launch a game through LB, the Wii controller vibrates once and stays connected fine.
