Dear List, I installed Linux Mint Mate 22 on a 2015 iMac. I had to plug in headphones on the back of the iMac to hear sound. If I selected speakers the sound would stop. So I up arrowed back to the headphone option and checked the box and plugged the headphones back in to hear sound. Well, I knew better, but I was messing around with the hardware settings, & guess what? Yes, you got it! I have no sound. Now I must wait until I can get someone to look at it. So, Once they get the headphones working again, Do you have any ideas of why headphones work but the speakers will not? Oh, I forgot to say that while entering the password at the log on screen, I get speech with the headphones, but after I hit the enter key to sign in, There is no more sound.
