I have been trying to get ALC298 working for a while now and wanted to
share my findings. This issue exist on all distros and is an ALSA
problem (not pulseaudio). Verified it when found a fix for the headphone
by using the kernel's early patching feature. To use this feature, write
a simple patch (instructions here
https://www.kernel.org/doc/html/v5.0/sound/hd-audio/notes.html):

[codec]
0x10ec0298 0x144dc169 0

[model]
auto

[verb]
0x1a 0x707 0xc5

and save it as /lib/firmware/alc298-sound-patch.fw then save:

options snd-hda-intel patch=alc298-sound-patch.fw,alc298-sound-
patch.fw,alc298-sound-patch.fw,alc298-sound-patch.fw

to /etc/modprobe.d/alc298-sound-patch.conf

Then reboot the machine and try your headphones. Next speakers!
unfortunately all three mixer pins in the hda codec are set to mute and
I'm working like a maniac to find a way of unmuting them, hoping that
would fix the speakers. Hope this helps someone.

Went from web development to system development over this issue. Some
may call that progress!

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:
