I checked Windows (updated to latest and including Realtek MEDIA) on
ASUS UX431FL laptop again.  Although it has two internal speaker pins,
there is only one set of internal speaker including left/right
channels.  And the audio test (Speaker Setup) only shows left/right
channels.  So, NID 0x14 can be disabled.
