My built-in microphone is not working properly on the programs I've tested it with like Google Chrome (Hangouts), Skype. But when I execute
pactl load-module module-loopback I get the feedback perfectly.
Google Chrome (Hangouts) does not receive any audio. Skype receives but outputs a very low and buzzing sound.
/etc/modprobe.d/alsa-base.conf to add
options snd-hda-intel model=auto and
options snd-hda-intel model=ideapad but that did not work (Internal microphone not working).
I am using Xubuntu 16.04.
