So, in my case, I've already switched to better DisplayPort cables, and the case for sound, so it happens on the LG 32 "4k UK550 Monitor, which has speakers on it.@LiveSorcerer : what are you using as cables and connections? I just worked through a problem in Big Sur beta where one of my monitors lost signal after turning Sidecar on. The monitor would only come on if I disconnected and reconnected the cable.
It turned out that I was using a DP > HDMI cable then an HDMI > DVI adapter! This is all I had lying around when I set up my rig. Although fine in Catalina, Big Sur didn't like that chain. Replacing the cable with a DP > DP solved it.
So maybe check your cables and connections, and maybe upgrade the cable too?
Both Dell UltraSharp U2419H use headset.
