Title:
Lenovo E50-80 inverted microphone not detected properly
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Wily:
Fix Committed
Bug description:
System: Lenovo E50-80 with Ubuntu 15.10. Tested with both kernel
4.2.0-22-generic from official repos and 4.4.0-040400rc6-generic from
Mainline Kernel repo.
Alsa information: http://www.alsa-
project.org/db/?f=3088f82a0cf977855f92af9db8ad406c04f71efa
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).
Adding model=inv-dmic to snd-hda-intel module options does not change
a thing.
Hope that helps, tell me if you need more info.
