I recently got a Samsung Frame 55 2019, installed the steam link app, was able to link it to my PC with the pin, and the connection seems to work fine (Steam goes into BPM and video is streaming fine) but I can't get my controllers to pass input through to my PC. I've tried a wired Xbox360 controller and a wired Xbox One controller. I've tried restarting both the TV and my PC, removing and re-adding the TV to Steam using the pin, and moving controllers around to each of the three US inputs on the TV. The controllers both work fine on the TV itself and in the Steam Link App, but as soon as the stream starts in Big Picture Mode, the controllers don't seem to pass any input (clicking buttons and directions does nothing in Steam BPM). They are not recognized in Steam controller settings via the TV but if I unplug them from the TV and plug them into the PC directly, they work fine. Anyone seen this issue before or have any additional steps I can try? Thanks!
