Built in speaker issue

Hi,

I just bought a brand new LG Gram. For the 2 minutes that I used Windows, the speakers worked fine. Since I installed pop OS the speakers don't work at all. I even tried reinstalling the whole entire OS and they still aren't working.

Thanks in advance!

This appears to be a common issue with the LG Gram. I found the following thread on the Linux Mint forums:

This lead me to an upstream bug report in the sof project (audio firmware):

https://github.com/thesofproject/linux/issues/4363

In this bug report, a user reported running a script that used the hda-verb command to configure the firmware worked around their issue and produced sound. Details about this script can be found on the Fedora forums here:

https://forums.fedoraforum.org/showthread.php?331130-Fixing-ALC298-audio-(no-sound-from-speakers)

Anyway, YMMV with this, but I guess this shows why buying hardware that supports Linux out of the box can make life easier. Good luck!
- Thank you so so so so much for all this research!!!!!!!!! But it's not letting me move the file to /usr/local/sbin and I also don't understand the step after that. Again, thank you so so much!!!!
  
  You may need to use sudo to move the file there since it is a system directory.
  
  Otherwise, if you could provide a screenshot or a paste of the error, we may be able to help you further.
  
  Genius! I got it to move but I don't understand the next step, and also the sound still isn't working even though I pressed 'run as program'.
  
  To test out the script, you can do sudo /usr/local/sbin/necessary-verbs.sh. See if that works.
  
  If it does, then I can explain about the Systemd unit.
  
  This is what I get when I type that command https://paste.sh/LO5_DWqx#lF9KhOFkNlg4x8kiK1DiHKeu
  
  Thanks again so so much!
  
  You probably need to install the package with the hda-verb command:
  
  sudo apt install alsa-tools
  
  After you do that, try to run the script again and see if it works.
  
  The script worked ran this time but there's still no sound. :-( Thank you so so so much though, I really appreciate your help! Let me know if you've got any other tricks up your sleeve ;-)
  
  Hmm. Unfortunately, if the script doesn't work then you probably need a different set of verbs for your particular laptop model. I'm not really sure how to determine which verbs to use. Sorry :|
  
  Actually, after a quick look, I found an entry on the Arch Linux Wiki:
  
  https://wiki.archlinux.org/title/LG_Gram_16_2-in-1_2023
  
  This says there might be a workaround here:
  
  https://bugzilla.kernel.org/show_bug.cgi?id=212041#c14
  
  It would be the same idea: download a script with a bunch of verbs, run the script, and see if the speakers work.
  
  Perhaps one of the scripts in that comment will work for your laptop.
  
  YOU'RE A GENIUS!!!!!!!!!!!!!!!!!!! THANK YOU SO SO SO SO MUCH!!!!!!!!!!!!! IT WORKS!!!!!!!!!!!!!!!! I used this https://gist.githubusercontent.com/eddy-geek/ef86267fbec87479aba905302909921a/raw/ script and it works!!!!!!!!!!!!!!! You're amazing!
  
  Now... Can you please explain how to make it not go away after a reboot...? Thanks!
  
  Great, I'm glad you now have sound :)
  
  To have the script run at boot, you need to create a service file:
  
  sudo gedit /etc/systemd/system/necessary-verbs.service
  
  That should open a text editor that you can write into. You can replace gedit with vim or nano if you prefer those.
  
  In that file, you want to put the following contents:
  
  [Unit] Description=Run internal speaker fix script at startup After=getty.target [Service] Type=simple ExecStart=/usr/local/sbin/necessary-verbs.sh TimeoutStartSec=0 [Install] WantedBy=default.target
  
  Once you save that file, you can enable it as follows:
  
  sudo systemctl daemon-reload sudo systemctl enable necessary-verbs.service
  
  Now, when you boot, this service will run that script and thus setup your audio.
  
  See if you can get that to work.
