I don't know if this will help, but I read a post somewhere (don't remember where) of someone who had troubles with the Ideapad 110S -- sound, touchpad, suspend, etc. -- after replacing Windows 10 with Stretch. Installing a newer kernel from Stretch-Backports rectified those issues along with non-free firmware in the Stretch Repos and/or proprietary drivers.
I have already the latest kernel version, but I would be interested having some details about these non-free firmware and drivers. Up to now, googling gave me nothing about that. best regards, -- Pierre Frenkiel
