Cannot record sound on ubuntu 16.04

    I have a dual boot system, where on windows i can both play and record audio, but on ubuntu I can only play it but not record. My laptop model is Acer Aspire VN7-592G-750P, sound card is HDA Intel PCH.
    I upgraded kernel to 4.16.9 and went through steps in https://help.ubuntu.com/community/SoundTroubleshootingProcedure, nothing helped. Here is output from alsa-info.sh: http://www.alsa-project.org/db/?f=f328a2b11572851af8bea176c866cb764243b3fc.
    And here is more diagnostic output: https://hastebin.com/orarixaneh.coffeescript (from cat /proc/asound/{version,cards,devices,hwdep,pcm,seq/clients}; ls -l /usr/share/pulseaudio/alsa-mixer/paths/; sudo rm /etc/asound.conf; sudo rm -r ~/.pulse ~/.asound* ;sudo rm ~/.pulse-cookie; sudo apt-get update; sudo apt-get install aptitude; sudo aptitude install paman gnome-alsamixer libasound2-plugins padevchooser libsdl1.2debian-pulseaudio; sudo lshw -short;ls -lart /dev/snd; find /lib/modules/`uname -r` | grep snd ;cat /dev/sndstat; lspci -nn; lsusb; sudo which alsactl; sudo fuser -v /dev/dsp /dev/snd/* ; dpkg -S bin/slmodemd; dmesg | egrep 'EMU|probe|emu|ALSA|alsa|ac97|udi|snd|ound|irmware'; sudo /etc/init.d/sl-modem-daemon status; sudo grep model /etc/modprobe.d/* ; sudo dmidecode|egrep 'anufact|roduct|erial|elease'; lsmod | egrep 'snd|usb|midi|udio'; pacmd list-sinks; aplay -l; sudo alsa force-reload; ubuntu-support-status ; sudo lshw -C sound).
