Public bug reported: My headphones aren't being detected, and don't work at all on my Dell laptop. My Ubuntu version is 24.04.2 LTS. I plug in my headphones and it should automatically detect and start using them.
Instead, my computer does not detect headphones. I know that this is a Linux problem because I can boot to Windows and my headphones work great. I've checked to make sure pulse and alsamixer work, and they seem to.
