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
Update 9/11/24
I have a fresh installation of Ubuntu 22.04.5 LTS and the problem remains. I have also install Ubuntu 24.04.1 and the problem remains.
Setting api.alsa.soft-mixer to true does not solve the issue. Source.
This bug fix also didn't fix my issue.
I have made a new bug report here. If you have the same problem please indicate that in the bug report.
Update 10/11/24
After installing alsamixer I've discovered that increasing the volume using the volume slider in the ubunt applet or using the keyboard shortcut, increases the master channel volume by 53% after one increase and to 100% after two increases. The speaker channel increases in constant small steps. The gif below shows what happens when pressing the increase volume key twice.
