MSI Laptop, no sound via headphone jack / no external sound

Hello out there,

I am on Ubuntu 24.04 and cannot get any sound out of the audio jack, only the laptop speakers do work. The Laptop is MSI 73vr 7rf. Edit: Actually, there is a very low output, barely noticeable. Seems like the amp works on line-out level.

lspci -v:

sudo dmesg | grep snd_hda_intel

What I’ve Tried:

Adding entries in etc/modprobe.d/alsa-base.conf

  • options snd-hda-intel model=headset-mode
  • options snd-hda-intel model=dell-headset-multi
  • options snd-hda-intel model=headphone-jack-pivots

And also

pulseaudio -k && sudo alsa force-reload

I tried

  • pavucontrol
  • alsactl restore
  • alsa force-reload
  • alsamixer

When using pulseaudio, it says

W: [pulseaudio] pid.c: Stale PID file, overwriting.
E: [pulseaudio] socket-server.c: bind(): Address already in use
E: [pulseaudio] module.c: Failed to load module “module-native-protocol-unix” (argument: “”): initialization failed.
E: [pulseaudio] main.c: D-Bus name org.pulseaudio.Server already taken.

I am really out of ideas. Can anyone help?
