I recently bought a lenovo ideapad s210 and installed Ubuntu 13.10 on it.
Overall it works pretty good, but I can't figure out how to get the internal microphone to work.
I've tried adding in lines to the
/etc/modprobe.d/alsa-base.conf file as has been suggested in this thread Lenovo Ideapad built-in mic not working in 12.04.
But still no luck.
How to fix this?
