Jack output not working on kubuntu 20.04

[Somix]

On my Dell laptop I changed the option "Microphone" to "Headset Microphone" in the Audio settings and all of a sudden my headset connector worked and played sound.
Strange because my laptop doesn't have a microphone connector and I just plugged in a bunch of speakers.

The solution I posted up here does exactly the same thing by removing the 'Microphone' option so you don't need to switch out of it every time you connect the headphones .

Most of recent laptops just have a single jack port for both in and out by the way .

I verified that this happens on my system as well, so i found a workaround that should do the work. Basically you need to disable the 'Microphone' port that it's enabled by default when you plug in headphones. To do this you can run the commands

cd /usr/share/pulseaudio/alsa-mixer/paths
sudo mv  analog-input-headphone-mic.conf analog-input-headphone-mic.config.backup

Then restart.

This only changes the name of the file leaving the option for you to go back if the method doesn't work.

You shoul'd verify fist that "analog-input-headphone-mic" is the port that's giving you problems, you can do that issuing the command:

pacmd list-sources

Perfect! Works like a charm! Nice find, I just have to remember to remove it when I upgrade or use an actual mic lol
