I've now gone through all the nodes (even unconnected ones) where any
kind of input source was possible and set them to internal mic one after
another, put on a boot override and rebooted every time. Some pins have
white noise, others nothing at all.
If this helps, on the side of Windows, device
Hi Raymond,
switching to internal mic on node 0x12 doesn't work, the channel only
has white noise (the sound you hear from an untuned radio). I'm now
going to go through all the unconnected pins in hdajackretask to see if
one of them works.

@Raymond (superquad-vortex2)
I don't think the jack is a multifuntion one, but even if it is,
plugging the external microphone in or out doesn't change anything. The
computer has a separate headphone/SPDIF jack next to the microphone
input.

Barry,
1. There is no real benefit of 16.04, as it now has an older kernel
(4.3) than is available for wily (4.4). It once had better Intel HD
graphics support, but now the support has landed in 15.10. I'm now
running Ubuntu 15.10 too.
2. I've already tried node 0x19 for the internal microphone,
I've gone through the nodes, now making sure to test each channel
separately, but still nothing. Anything else we could try? I'm pretty
sure the microphone is not in the Realtec ALC255 protocol, but still
connected to the Intel sound card.

I see, if support has been added, can I enable/try it somehow?

Title:
Alsa not detecting internal microphone
This bug does at least affect all the Acer Aspire V Nitro series
laptops. Basically it affects every system, which has a Realtek ALC255
sound card and the internal microphone not directly connected to it
hardware wise. Once more, I have the Acer Aspire VN7-792G and the
suggestion in post #26 can't
The suggested fix in Raymond's post #26 doesn't work. This computer has
no combined audio port (now tested), and enabling dell-headset-multi
disables the separate external microphone port as well. Internal
microphone still not recognized.
