Alright, I'm thoroughly confused now. When I boot the Quantal live CD, the problem is gone, the speakers get muted as they should be.
However, I still can't get it to work when I downgrade the kernel to the same version used on the CD. I even tried downgrading ALSA and Pulseaudio as well to no avail. I don't remember touching any config files that belong to the sound subsystems, but that's the only explanation I can come up with at the moment. I'll probably try re-installing the damn thing and hope it goes away. Thanks anyway for the support! ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1224087 Title: [Fujitsu Esprimo Mobile D9500] No auto-mute with Intel HD Audio Status in “linux” package in Ubuntu: Invalid Bug description: Hello, since upgrading to Ubuntu 13.04, I noticed that the line-out channel does not get muted anymore when I plug my headphones into the headphone jack on the laptop. When plugging the headphones into the jack located on the port replicator, the line-out channel _does_ get muted. (The port replicator was not connected when I gathered the attached diagnostic data). To isolate the bug, I installed the kernel packages from Quantal (linux-image 3.5.0-28), rebooted and tried to reproduce the problem. I was unable to do so, so I am pretty confident that the bug is somewhere in the kernel, probably the snd-hda-intel driver module. I also checked to see if the bug was fixed in the current mainline kernel using the Mainline Kernel PPA. As of Kernel 3.11, the bug still persists. Please let me know if you need any more information. Steps to reproduce: 1/ Cold boot the system 2/ play audio => result: audio can be heard on the speakers 3/ plug in headphones 4/ play audio => result: audio gets played on _both_ headphones and speakers Thank you!
