Microphone is not working on Ubuntu 16.04
Solution 1
I had this exact problem. My solution:
1) open PulseAudio control
2)go to the configuration tab.
3)select analog stereo duplex to use the computers built in audio&mic
Solution 2
My issue was a small variation to OP's problem - I have a headset (combined stereo headphones and mic) jack.
First use hdajackretask check that the problem is not related to the jack (eg see user47206's solution). For me, my jack was correctly detected as 'Headphone'.
- Press Ctrl+Alt+t to access the terminal.
- Type
cat /proc/asound/card*/codec* | grep Codec
in the terminal and take note of the codecs listed. - If there are multiple codecs listed, determine which one relates to your headset jack. For me there were two listed - one related the the video card (
Codec: ATI R6xx HDMI
) and another related to the sound card (Codec: Realtek ALC3861
). In my case, I was interested in the sound card because I was connecting to the PC headset jack and not a HDMI device such as a PC monitor. - Look up the HD-Audio model for your codec in HD-Audio Codec-Specific Models. For my headset jack, the best fit was the dell-headset-multi model.
- Type
cd /etc/modprobe.d/
in the terminal. - Type
sudo cp alsa-base.conf alsa-base.conf.bak
to backup the file before editing. - Type
gksudo gedit ./alsa-base.conf
to edit the file. - Insert this line at the bottom of the file
options snd-hda-intel model={HD-Audio model for you codec}
. For example, for it me it wasoptions snd-hda-intel model=dell-headset-multi
. - Save file and reboot.
Solution 3
I did it guys!
sudo gedit /etc/modprobe.d/alsa-base.conf
- Look for the
options snd-usb-audio index=-2
and change it tooptions snd-usb-audio index=0
- Add
options snd-hda-intel model=auto

I had a similar issue and tried every answer I found online with no luck. Finally, from alsamixer I changed the Channel option which was 6ch, to 4ch or 2ch, and the mic started capturing input, don't know why...
Solution 5
Very easy solution.
tl;dr : press red volume icon as shown in screenshot image above.
I had the same problem. On Ubuntu 16.04.3 LTS, KDE
My solution:
1) Go to "Audio Volume Settings"
2) Select "Input Devices" (Tab)
** in the top right corner the sound icon is marked in red. As mute.
3) Press (left click) the red sound Icon (mentioned above)
4) Press OK
Check if problem is solved.
If not make sure to choose the right option from the port options in the Input Devices Tab (I choose Internal Microphone) and make sure the volume percentage is above 0%, preferably for the test set to 100%.
It was the internal microphone on my laptop. Meaning the built-in mic in my laptop.

I have problem with my HDA Intel PCH audio under Ubuntu 16.04. I never had any problem with speakers, however my microphone is not working.
When I plug microphone in jack, system reacts and it looks like microphone is in, however no single bar appear in any settings in "Input levels". The microphone works fine, just tested on notebook with Ubuntu 12.04.

Admin about 7 years@ForDev - what laptop do you have? Do you see your mic in audio settings or in

Admin about 7 years@ForDev - you mean this was fixed with Debian rolling? What kernel version please? Maybe I'll stumble into this in the future on that Asus and using a newer kernel may be the way to go.

MHT over 6 yearsI've found that even though my setting was Analog Stereo Duplex, switching to another setting and then back to duplex solves the problem.
