Kernel also has a model alias name for ALC298_FIXUP_SAMSUNG_AMP patch for other systems

ALSA developers at bugzilla.kernel.org can create a Kernel patch if the modprobe model option works
or if there is a working sequence of hda-verbs

ALSA developers cannot work out the correct hda-verbs needed for every laptop model
Users with unpatched hardware can get a working configuration of hda-verbs from a Windows sound driver running in a virtual machine
