I'm not sure whether FM2018 is on a netbook. Rather my guess is it's a digital-mic component by FortMedia together with their software library for SAM handling. BTW, a simple "fix" for the mono capture problem, you can patch the config file for HD-audio in alsa-lib like below. Then the first channel will be used for mono capture instead of averages. Give it a try. (But, this won't fix programs that prefer "hw" access such as pulseaudio, of course.)
