Public bug reported: My Dell Inspiron 6400 laptop has HDA Intel audio with a STAC9200 codec. It has speakers and a headphone jack. Previously when the headphone jack was unplugged sound came from the speakers, and when headphones were plugged in, sound came only from the headphones. In Ubuntu 22.04, when I plug in the headphones, sound comes from both the speakers and headphones.
ALSA has the "Auto-Mute" feature, which mutes the speakers when headphones are plugged in. The problem is that Pulseaudio disables this feature. Every time I plug in headphones, I need to again re-enable that feature using alsamixer to stop sound from speakers. The problem seems to be this unfixed bug in Pulseaudio: https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1297 ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: pulseaudio 1:15.99.1+dfsg1-1ubuntu1 ProcVersionSignature: Ubuntu 5.15.0-25.25-generic 5.15.30 Uname: Linux 5.15.0-25-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.11-0ubuntu80 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: bgjenero 15920 F.... pulseaudio CasperMD5CheckResult: unknown CurrentDesktop: XFCE Date: Wed Apr 13 00:57:54 2022 SourcePackage: pulseaudio UpgradeStatus: Upgraded to jammy on 2022-04-04 (8 days ago) dmi.bios.date: 06/13/2007 dmi.bios.release: 1.7 dmi.bios.vendor: Dell Inc. dmi.bios.version: A17 dmi.board.name: 0XD720 dmi.board.vendor: Dell Inc. dmi.chassis.type: 8 dmi.chassis.vendor: Dell Inc. dmi.ec.firmware.release: 1.7 dmi.modalias: dmi:bvnDellInc.:bvrA17:bd06/13/2007:br1.7:efr1.7:svnDellInc.:pnMM061:pvr:rvnDellInc.:rn0XD720:rvr:cvnDellInc.:ct8:cvr:sku: dmi.product.name: MM061 dmi.sys.vendor: Dell Inc. ** Affects: pulseaudio (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug jammy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1968827 Title: Pulseaudio disables auto mute, so speaker sound continues when headphones plugged in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1968827/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
