No sound from speaker on LG gram 2023 (i7-1360P)

in flag

Just bought a LG Gram 16Z90R-G.AD78F EVO that is the brand new Lg Gram with new i7-1360P, instead of previous i7-1260P (my previous laptop, no sound issue).

After installing Ubuntu cinnamon 23.04, everything works well except I can't have any sound from the speaker, it work well on HDMI output or jack, but switching to internal speaker don't output any sound.

I've tried to follow a lot of tutorial on the web, like this one

I have a similar problem with the 14-inch model of LG Gram 2023. Did you manage to find a solution?
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
