Hi there. Kubuntu won't detect the existence of a headphone port, thus won't autoswitch to that when headphones are plugged in.
Lenovo Flex 14API - https://www.microcenter.com/product/...mputer---black
This bug affected me on 19.04 as well. There's a side issue where I have to run the old 5.0.0-32-generic kernel or there's serious video lag and frequent hard lockups, especially on attempting to suspend to RAM.

04:00.6 Audio device: Advanced Micro Devices, Inc. [AMD] Family 17h (Models 10h-1fh) HD Audio Controller

The port doesn't show up at all in any control panel - thinks there's only speakers. So, is the wrong device driver being used for my card or?
Thanks in advance for any help.
