I have same problem on Asus X550L.
When I change microphone port in 'pavucontrol', from microphone(internal) to microphone(unplugged), i can hear sound from internal microphone, but its very, very quiet, even with maximum boost of 11.00dB
External microphone dose not work at all.

Had the same issue with an ASUS S551LN (Realtek ALC233, Internal Mic, combo microphone/headphone jack).
After playing around a lot, the following settings in the alsamixer finally seemed to do the trick:

1) Playback->Mic: 100%
2) Playback->Mic Boost: 0%
3) Capture->Capture: 100%
4) Capture->Mic Boost: 0%

This resulted in what looked like a very low mic level in pulseaudio,
but the internal mic works fine. Changing any mic setting from
pulseaudio immediately increases the boost in alsamixer and kills mic
input.

Hope it's of some use
