I have the same issue with my ALC892. The only workaround is to use the hdajackretask, however this tweak disables either speaker or microphone.
Does someone know if this bug will be fixed as it have been reported in 2016 ? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1577599 Title: [CM1855, Realtek ALC892, Green Line Out, Rear] Sound is distorted / Audio Notification unstable (Popping in/out) Status in alsa-driver package in Ubuntu: Confirmed Bug description: For a better explanation, here is a video I've made. https://youtu.be/8q092XpLT-Y For further diagnostics, here is a ubuntu forum post I've made. http://ubuntuforums.org/showthread.php?t=2322708 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 4.4.0-21.37-generic 4.4.6 Uname: Linux 4.4.0-21-generic x86_64 ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC2D0c: deviantxs 1672 F...m pulseaudio /dev/snd/controlC2: deviantxs 1672 F.... pulseaudio /dev/snd/controlC0: deviantxs 1672 F.... pulseaudio /dev/snd/controlC1: deviantxs 1672 F.... pulseaudio CurrentDesktop: Unity Date: Mon May 2 16:35:54 2016 InstallationDate: Installed on 2016-04-30 (2 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:SB failed Symptom_Card: Built-in Audio - HDA ATI SB Symptom_Jack: Green Line Out, Rear Symptom_Type: Digital clip or distortion, or "overdriven" sound Title: [CM1855, Realtek ALC892, Green Line Out, Rear] Sound is distorted UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 08/20/2013 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 1501 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: CM1855 dmi.board.vendor: ASUSTeK COMPUTER INC. dmi.board.version: Rev 1.xx dmi.chassis.asset.tag: To Be Filled By O.E.M. dmi.chassis.type: 3 dmi.chassis.vendor: To Be Filled By O.E.M. dmi.chassis.version: To Be Filled By O.E.M. dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr1501:bd08/20/2013:svnASUSTeKCOMPUTERINC.:pnCM1855:pvrTobefilledbyO.E.M.:rvnASUSTeKCOMPUTERINC.:rnCM1855:rvrRev1.xx:cvnToBeFilledByO.E.M.:ct3:cvrToBeFilledByO.E.M.: dmi.product.name: CM1855 dmi.product.version: To be filled by O.E.M. dmi.sys.vendor: ASUSTeK COMPUTER INC.
