Public bug reported: PulseAudio detects internal microphone but cannot receive any sound from it.
WORK-AROUND: Issue command: $ pactl set-source-volume 1 0% 100% or "Install the pavucontrol application, start it and go to the "Input Devices" tab. Unlock the channels (there is a keylock icon), then mute the right channel while keeping the left channel at the volume you want. If the internal mic is now working correctly, you have an inverted internal mic, so that your right channel cancels out the left one." source: https://bugs.launchpad.net/ubuntu/+source/alsa- driver/+bug/1002978 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: pulseaudio 1:8.0-0ubuntu3 ProcVersionSignature: Ubuntu 4.4.0-38.57-generic 4.4.19 Uname: Linux 4.4.0-38-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: chris 1737 F.... pulseaudio chris 10382 F.... alsamixer Date: Thu Oct 6 10:47:52 2016 InstallationDate: Installed on 2016-10-05 (1 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) SourcePackage: pulseaudio UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/15/2016 dmi.bios.vendor: LENOVO dmi.bios.version: D5CN46WW dmi.board.asset.tag: NO Asset Tag dmi.board.name: VIUU4 dmi.board.vendor: LENOVO dmi.board.version: SDK0J40700 WIN dmi.chassis.asset.tag: NO Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo ideapad 300-17ISK dmi.modalias: dmi:bvnLENOVO:bvrD5CN46WW:bd03/15/2016:svnLENOVO:pn80QH:pvrLenovoideapad300-17ISK:rvnLENOVO:rnVIUU4:rvrSDK0J40700WIN:cvnLENOVO:ct10:cvrLenovoideapad300-17ISK: dmi.product.name: 80QH dmi.product.version: Lenovo ideapad 300-17ISK dmi.sys.vendor: LENOVO ** Affects: pulseaudio (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug xenial -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1631043 Title: Internal microphone does not work due to phase inversion Status in pulseaudio package in Ubuntu: New Bug description: PulseAudio detects internal microphone but cannot receive any sound from it.
