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.
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:
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!!!!
