[Bug 1474254] [NEW] Microphone doesn't record any sound in VoIP apps like Skype

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

[Impact]

I am unable to perform any sort of communication involving VoIP on this
Lenovo computer.

[Test case]

I've tried apps like Skype, Hangouts (web), Telegram Desktop, no sound
is recorded, the other side cannot hear me or if they can, then silent
and distorted.

Recording voice via Audacity works flawless.

Previous kernel versions were unaffected at some point, then the bug
appeared I believe in k3.16.*, k3.13.* should not be affected.
Everything from 3.19.* upwards is.

[Troubleshooting]

This has been discussed via Ubuntu Forums in suspicion it might be
related to recent BIOS upgrades/changes, but was concluded it should
have no impact http://ubuntuforums.org/showthread.php?t=2285503

I am attaching a test recording I obtained following the instructions
