I recently set up a dual boot laptop (Lenovo Yoga pro 7) with Ubuntu 22.04 and I'm having troubles with the volume control. At the moment the system volume slider doesn't change the volume of apps like Spotify, Firefox, etc. I can change those volumes manually in the sound app but the system volume slider is completely useless. At zero is silent and at the lowest volume is whatever the volume of the app playing music is. This happens only when playing sounds through the laptop speakers, when using bluethoot headphones there is no problem.
This is the output of lspci -v | grep -A7 -i "audio"

I tried adding options snd-hda-intel model=auto to alsa-base.conf (as suggested in here) and also the solution here. Any help is appreciated also let me know if more info is needed.
Update 27/09/23: Adding element master before element PCM doesn't work (as suggested here and here).
Adding
[Element Master]
switch = mute
volume = ignore
just before
[Element PCM]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right
