To add to #9, as well as the headphones being detected after running alsa-info, I can confirm that they still work as expected after detection.
As this may be a bug introduced by a kernel change, the current kernel running is 5.4.0.42.45 (generic, x86_64), whereas the previous one I was running when I didn't see this bug was 5.4.0.40.43. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888992 Title: [Realtek ALC892, Green Headphone Out, Front] Not detecting/switching to front jack after plugging in headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1888992/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
