No sound from speaker on LG gram 2023

[omidhatami]

I have bought an LG Gram 14Z90RS-K.ADW9U1 EVO that is the brand new LG Gram with a new i7-1360P. After installing Ubuntu 23.04, everything works well except I can't have any sound from the speaker, it works well on HDMI output or jack, but switching to an internal speaker doesn't output any sound.

It seems to use a Realtek ALC298 codec. I have included the alsa-info output here. Can someone here help me to resolve this issue?

Thanks for your help.

It can be a challenge with new hardware and the Linux Kernel and available codecs. It can take a few months to a couple of years for hardware support.

Late for this thought, as you have brand new hardware, but GNU/Linux works best on hardware a couple years old, support is in place by that time.
