Public bug reported: 07 Dec 2012 I installed the latest ubuntu 12.04 updates on my Pavilion dv6 laptop. This came with a kernel update 3.2.0-35
I always leave my headphones connected to the jacks (left side, mic=red, ears=black). I don't use the built-in speakers very often and don't unplug my headphones. I noticed something strange after latest package updates and restarting because there is now a light on the keyboard f11 / mute key showing the sounds is muted. This didn't happen before. If I unplug the headphones then the light goes out and it unmutes. I can hear sound through the laptop speakers. Both +/- volume buttons work and mute key work and the OSD displays correctly. When I reconnect the headphones the light comes on f11 mute key and the sound disappears. The OSD still shows the master volume as 100% I went into system setttings.... sound... changed the connector from Headphones to Speakers and it seems to fix the problem but this is not permanent, as I now have to do this after every reboot. It used to work perfectly well before Yesterday so is there a way I can get it back the way it was? Thanks for any help. >lsb_release -rd Description: Ubuntu 12.04.1 LTS Release: 12.04 >uname -a Linux HPdv6b55sa 3.2.0-35-generic #55-Ubuntu SMP Wed Dec 5 17:42:16 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux >lspci | grep Audio 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) I'm following the sound bug reporting guidelines from here https://wiki.ubuntu.com/DebuggingSoundProblems ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: alsa-base 1.0.25+dfsg-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-35.55-generic 3.2.34 Uname: Linux 3.2.0-35-generic x86_64 NonfreeKernelModules: fglrx AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
