I downloaded steamlink for my raspberry pi running emulation station using sudo apt install steamlink and was able to boot it up. For awhile, I had no issues, but recently, when I connect to my computer, my computer opens big picture mode, my steamlink connects and I can move around the screen using my controller, but the video and sound don't show up on the tv.
I would expect to see the steam big picture
