Apple Event: May 7th at 7 am PT
When I opened my laptop this morning, the sound wasn't working. When I press the sound buttons, the line goes up and down but there is no clicking noise and it doesn't work. It was working fine last night. I restarted my laptop, hoping that would help. I heard the restart noise, but the normal sound still doesn't work.
I would really appreciate a solloution, and I hope this makes sense.
