Public bug reported:

I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
Aspire VN7-792G and noticed, that the internal microphone doesn't work.
The computer has been released a couple of months ago and it's Intel
Skylake -based with a Sunrise Point -based motherboard.

INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
detected. Currently using Ubuntu 16.04 for proper hardware support.

Alsa reports the audio device to be:

Card: HDA Intel PCH
Chip: Intel Skylake HDMI

The speakers are working fine, but both alsamixer and pavucontrol
(Pulseaudio Volume Control) raport the unplugged external microphone
connector as the only sound input.

I have tried many of the alsa model configurations (options snd-hda-
intel model=something) without success, alsa finds only the microphone
jack, which works fine when I plug an external microphone in it.

Here's some info:

lspci | grep -I audio:

00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
HD Audio (rev 31)

cat /proc/asound/cards:

0 [PCH            ]: HDA-Intel - HDA Intel PCH
                            HDA Intel PCH at 0x84320000 irq 128

And a clip from dmesg | grep snd:

[    3.019164] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915])

[    3.047514] snd_hda_codec_realtek hdaudioC0D0:      Mic=0x1a

One problem is that I can't find any model options (options snd-hda-
intel model=something) or other parameters for the card's model
(ALC255), I suppose this issue is relatively new.

Title:
  Alsa not detecting internal microphone [ALC255]
