I've already tried looking through all sound options, turning it on and off, digging a bit deeper and haven't found anything. The headphone jack doesn't work. Here's the thing, I think it's some kind of settings issue, but just something I can't find. I had my brother take a look before leaving because he's a lot more tech-savvy than I am. He couldn't figure out the issue either.
The really strange thing is that no sound works EXCEPT for the start up and closing sounds of Skype. When I try to call someone with it though, nothing. When I try to use any other program, nothing. I've dug through sound settings in each of the programs that I really use sound for (iTunes, Chrome, Skype) and I can't figure it out. Hence why I'm reaching out for help.
