I hooked my computer up to my tv via an HDMI cord. I am trying to watch a movie on Google Play. It used to work fine, but now it doesn't. I checked m audio settings and it it is acknowledging the tv as a sound output. I also did a sound test and it played fine through the tv, but when I try the movie, music, youtube, or anything it won't play. I'm not sure what is wrong though. My computer is a Hp Probook 4540 and the tv is a Sony Bravia. Is there a way to resolve this issue?
