Hi Park, There is a confusion. We don't have a platform to cross-check.  Could
you please double confirm,
when you record audio stream from UI, which capture PCM device being used ?  Or
else you can do
command line testing using arecord and confirm the pcm device.

As per our CE team, the platform you have mentioned uses different hardware
configuration.
Could you please double confirm exact model details?  Share us dmidecode and
acpidump.
Share us aplay -l and arecord -l listing.
