The sound on my macbook has locked itself. Why has it done that and how can I fix it?
You know it does that weird thing when headphones are in the sock half in/half out...It's like that all the time. When I try to adjust the sound it comes up with the speaker sign,as it should, but there's a white 'stop' sign too. If anyone can help that'd be great as I pretty much rely on sound for everything! Thankss x
