Same problem with Samsung Galaxy Book Flex 930QCG.
The Samsung Galaxy Chromebook and Galaxy Book Flex look very similar,
the sound chip should be the same, the Chromebook is open source and
also uses the Linux kernel, can we refer to the Chromebook code?

Title:
[950SBE/951SBE, Realtek ALC298, Speaker, Internal] No sound on
internal speakers, very very quiet on headphones
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
I've been googling this issue for 10's of hours and tried many things.
Relase of Ubuntu: 19.10
Expected outcome: Music plays on the internal speakers and headphones.
Actual outcome: I can barely hear audio using headphones with volume
turned up to 150%. Absolutely nothing comes out of the speakers. (The
speakers sound great under Windows 10.)
Complete alsa-info output is attached, but here are some snippets:
