Do I have to downgrade my system from Dingo to Cosmic in order to test this in Cosmic, to keep my bug from being closed?

This fix is specific to a board which is defined by DMI strings. My machine is a LattePanda board, which uses a "chtrt5645" device as a sound card. It has a single headphone output jack, which I think is a TRRS jack, with a mic input, such as is normally used on phones. When I don't have headphones plugged in, the system thinks headphones *are* plugged in. Gnome Control Center shows my audio device as being headphones. If I insert a headphone connector partway into the jack, I can even get sound in the headphones. But if I plug the headphones all the way in, the system decided that I have *un*plugged the headphones, and switches output over to "Speaker". The system doesn't actually have a speaker, only a headphone jack. And when the system switches over to "Speaker", I get no sound out of the headphones, even if I open "pavucontrol" and swap over to "Headphones (unplugged)" on the "Output Devices" tab. This is what "pacmd"'s "list-cards" command says with my headphones *unplugged*: 2 card(s) available. index: 0 name: <alsa_card.pci-0000_00_02.0-platform-hdmi-lpe-audio> driver: <module-alsa-card.c>
