I tried to play a video on Youtube and realised that there was no audio.

 

So I opened up iTunes to see if it was just something wrong wit youtube and it said something along the lines of 'itunes has detected a problem with your audio configuration, the playback of some songs/videos may be affected. And it doesn't even play the files.

 

I haven't had any problems with this before.

 

Any help would be greatly appreciated.
