For some reason, whenever I go to youtube, the sound on the youtube video is automatically on the mute setting. I try pressing the speaker icon, but it usually doesn't respond (though sometimes after numerous tries I'll be able to get it off the mute setting). This is new, and I'm not sure why this is happening.
ETA: I think it's just my old crappy mouse giving me problems. When I pressed extra hard on the button I was able to unmute it.
