I've gone through many of these forums and solutions for this problem but none of them have worked. My internal speakers stopped working and this has happened before but it was solved by the easy-peasy headphone trick that is popular on those forums. But now it doesn't work. I've actually done it maybe a dozen times and it still doesn't work. I'm starting to think it's because my cat spilled water on it but I still don't think that's the case because this problem has happened before. I've tried restarting the computer and looking at the system preferences. The internal speakers don't even come up as an option on the output. Can someone help?
