Title:
Lenovo G50-45 inverted microphone not detected properly
Status in linux package in Ubuntu:
Expired
Status in pulseaudio package in Ubuntu:
New
Bug description:
System: Lenovo G50-45 with Lubuntu 16.04
Alsa information: http://www.alsa-
project.org/db/?f=5e8ab749ddf4f0a7e4ae8f3ce678ddb9cb12c89f
Internal microphone does not pick up sound by default. When I mute one
channel, it works (this is not a good workaround since some application, such
as Facebook Messenger, unmute both channels and set them to the same level
automatically).
