Ubuntu – Microphone NOT working on Ubuntu 16.04

Today I decided I will install Ubuntu 16.04 alongside my Windows 10 in a dual-boot system. After installing everything, I decided to install Discord to talk with some friends, then I noticed that my mic wasn't working. I thought that there may be a problem with my Discord install, but there isn't after I checked that my mic wasn't working in many more programs (including System Settings > Sound where no sound was showing up).

I also have to mention that my sound is working completetly fine. It's just the mic that's not working. Microphone is part of my headset (CREATIVE Sound BlasterX H7).

I checked all the forums and tried many different solutions. Some of them were:

• checking that the microphone isn't muted (it isn't);

• checking my settings in the pavucontrol panel. Trying to split the channels and lowering each channel at a time to check if the mic will work after that;

• looking at the Configuration panel in pavucontrol and setting it to Analog Stereo Duplex

• looking at the alsamixer and checking that the mic isn't muted (look at the pictures below) [I may have overlooked this step]

• trying to install a new vivid alsa dkms driver

• restarting the audio drivers

I am 100% sure my microphone is functioning, since I can use it without any problems on Windows 10 or on any other machine.

Imporant specs [since there may be a problem with my computer's drivers]:

i7-6700k Skylake / z170x gaming 7 Gigabyte / 2 monitors each having its own speakers
