so I recently got a new laptop (matebook 13 2019) and naturally installed kubuntu on it, everything went super smooth until i noticed that the headphone port wasnt working and it ended up being an issue with it not detecting when a device was plugged in and was fixed quite easily by changing one line in a conf
(sudo echo “options snd_hda_intel model=dell-headset-multi” >> /etc/modprobe.d/alsa-base.conf)
but after a couple hours and 1 reboot later i noticed that the audio was no longer working when i plugged in headphones until i changed the microphone from “microphone” to either “internal microphone” or “headset microphone” which can be quite annoying every time i want to plug in some headphones and watch a youtube video. any help would be greatly appreciated 
(also im fairly new to the linux community so please be gentle)
