After running Software Updater on Ubuntu 22.04 I have a blinking prohibit icon at the bottom of my desktop. The keyboard works fine. After several attempts, I found out that the problem is the headphones. As soon as I have unplugged the jack the prohibit icon disappeared. As soon as I have plugged the jack back in, the icon magically reappeared. I tried changing the headphones but the problem persists. Do you have any idea how to fix it?
