Pulseaudio no sound from speakers

Looks like it might be the same bug that is known in Ubuntu also:


This wiki has a suggestion for a workaround:


The workaround is to edit the /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf file like this:

[Element Headphone]
switch = off
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

[Element Speaker]
required-any = any
switch = mute
volume = off

and then to restart pulseaudio (in Debian 10 it's implemented as a systemd per-user service):

systemctl --user restart pulseaudio.service

If I understand the workaround correctly, it looks like the volume/mute controls for the front speakers and headphones may be somehow miswired/cross-connected.

The hdajackretask tool in package alsa-tools-gui might be helpful too: if you can find working override settings for your laptop model, you should probably contact the Linux audio driver developers to report your findings, so the override can be made to apply automatically to that particular system model.

MSI GL73 apparently uses the same ALC1220 sound codec and also needed the same fix in sound routing as Clevo P950. As a wild guess, you might try adding a file named /etc/modprobe.d/sound-fixup.conf with the following content:

options snd-hda-intel model=clevo-p950

Then run update-initramfs -u as root to make sure the change will be effective in early boot also, then reboot and see if it results in an improvement. If MSI has wired your model the same as the GL73, this might fix it. If not, delete the /etc/modprobe.d/sound-fixup.conf file and run update-initramfs -u again to fully get rid of the option.
