No Microphone picked up on Ubuntu 16.04 on Macbook Pro
Solution 1
I was able to fix it by
Adding the following line to the bottom of /etc/modprobe.d/alsa-base.conf: options snd-hda-intel model=mbp101
Solution 2
I had the same issue with my Macbook air running KDE Neon (ubuntu 18).
Here is what fixed my issue:
1. Added the following line to /etc/modprobe.d/alsa-base.conf
options snd-hda-intel model=mba6
To find the model I first ran:
cat /proc/asound/card*/codec* | grep Codec
Then searched HD-Audio Codec-Specific Models to find the corresponding model.
2. Changed my sound card profile from Analogue Stereo Output
to Analogue Stereo Duplex
Check here for an image (I don't have enough reputation)
I also disabled my HDMI sound (top device in picture), though I don't believe this had any effect
3. Reboot!
This worked for me, hopefully this is useful to somebody else.

I am running Ubuntu 16.04 LTS on a Macbook Pro. Everything is going great but my internal microphone nor headphones with microphone are being picked up.
I have tried: checking the hardware works on another OS, Alsamixer, PAVU (Pulsa Audio Volume Control all to no avail.
All of these show an internal microphone etc. but dont pick up anything. Is there a driver I need to install perhaps?
Here is this that may help?
$ cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xa0610000 irq 37
Mainly trying to use in Skype and Discord but don't think that makes a difference
Thanks

JOduMonT almost 3 years@SadeghAlirezaie Actually, how he got lucky is Mac was a 10,1 or he followed the step of the Doug answer. For me, the answer is mbp81 because my Mac is a version 8,1, Look under your Mac, you will see a number starting with a, such as a1278, then search here: everymac.com/ultimate-mac-lookup
