This appears to be a common issue with the LG Gram. I found the following thread on the Linux Mint forums:
https://forums.linuxmint.com/viewtopic.php?t=401957
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
sudoto 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-verbcommand: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:
That should open a text editor that you can write into. You can replace
geditwithvimornanoif you prefer those.In that file, you want to put the following contents:
Once you save that file, you can enable it as follows:
Now, when you boot, this service will run that script and thus setup your audio.
See if you can get that to work.
Thank you so so so much for taking the time to write that! But before I read you message I actually had to restart my laptop for a different reason and the sound still works. This is very weird because it said in the link to the script that it wouldn't still work after a reboot, but it is. Thanks again so much!!!!
