I was playing music in media player and paused it using a button on my keyboard. I then opened up Movie Maker but when I played a video there was no sound. I seem to have lost all sound.
I've tried Movie Maker, Media Player and Youtube and there's no sound at all. I've turned the volume up, it's certainly not on mute, the speakers work perfectly fine and it was all fine just minutes ago before I paused my music.
Why have I lost the sound and how do I get it back? Really don't want to have to restart the computer to get it back unless I have to.
