Hi, I'm new to Raspberry Pi and Linux, so bear with me if the solution is painfully obvious.
I followed the instructions and was able to install Moonlight and Luna on my Raspberry Pi. There were a few hiccups, but I finally got everything installed and and paired up with my host PC. Once paired I started Luna and it recognized my games. However, when I attempt to launch a game, it opens up on my host computer and not my tv (which is the display for my raspberry pi.) I tried searching for a solution, but haven't come across one that has worked yet.
A user, Spamm00r had this issue about a year ago (here), I tried his solution of using the command "sudo modprobe snd-bcm2835" but that didn't seem to work. (at least after entering that phrase into the command line, it didn't seem to make any difference.)
I'd really appreciate any suggestions or tips, thanks!
