The response was “The MIC is bulit into the in mainboard of the unit.”
Does that help? Happy to ask again if that still doesn’t answer your
question.

not asking if the codec directly connects to DSP, please ask if internal
mic connects to DSP or codec?

The response from Acer was that "the realtek codec is directly connected
to the DSP". Is there anything else I should ask them?

Could you ask the Acer what is the hardware design for the internal mic
on this machine? Does the internal mic connect to the realtek codec or
directly connect to the DSP in the PCH?

Sorry you are right. I'm not really familiar with alsa much but triaged
a few similar issues recently and tried to help a bit.
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-
next.git/tree/sound/pci/hda/patch_realtek.c has mention of hacks with
the ALC256 but for asus configs, unsure
Hi Sebastien,
I added the line as suggested and rebuilt the driver. Unfortunately this
didn't resolve the issue.
I notice the added line references the ALC286 chip rather than the
ALC256 - is there likely to be a different pin mapping between the two
chips? Are there any variations on the above
It's just adding that line in the right place in your patch_realtek.c
and rebuilding

Hi Sebastien,
Yes I would be happy to manually patch the driver. Is it just a case of
replacing my existing patch_realtek.c file with the one in the branch
and adding that line? Or is the patching process more involved?
Thanks,
James

Do you feel like manually patching that in the driver you build to see
if that fixes the issue?
