I have the same issue after a recent kernel update. Not sure if the cause is the same, but after about 5 hours looking to the issue, the mostly likely cause seems well explained on this bug comment: https://bugzilla.kernel.org/show_bug.cgi?id=208061#c5
In my case. Distro v: 20.04.6 LTS Kernel v: 5.15.0-71-generic I'm hoping the upstream kernel will have the regression with jack sensing fixed. Via the CLI, I can use alas directly and the sound card works fine, but with pulseaudio, it claims the ports are not available / connected and refuses to default sound output to the analogue line out port because jack sensing fails and even in gnome audio settings it won't list analogue audio as an option. ** Bug watch added: Linux Kernel Bug Tracker #208061 https://bugzilla.kernel.org/show_bug.cgi?id=208061 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1897456 Title: [Z390 M, Realtek ALC892, Green Line Out, Rear] No sound at all Status in pulseaudio package in Ubuntu: Confirmed Bug description: The desktop speakers not working.
