Public bug reported: 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. ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1529624 Title: Lenovo E50-80 inverted microphone not detected properly Status in alsa-driver package in Ubuntu: New Bug description: System: Lenovo E50-80 with Ubuntu 15.10.
