I still don't understand. I never "unplugged." I do not use headphones or earbuds. I use only the laptop speakers.
It is reboot that causes the value to toggle, and the speakers to be disabled. This behavior started with the recent upgrade to 12.04. Here is the current value of 33 from amixer -c0 contents: $ amixer -c0 contents numid=33,iface=CARD,name='Headphone Jack' ; type=BOOLEAN,access=r-------,values=1 : values=on I just tried plugging and unplugging earbuds into the headphone jack (had to find it first) several times. There is no change in the amixer output for 33. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1085552 Title: sound output connector reverts to headphones on boot Status in “pulseaudio” package in Ubuntu: New Bug description: On each boot, System Settings->Sound->(Output Tab)->Connector comes up as Headphones. Sound does not work until changed to Speakers. Setting holds through suspend but not a reboot. On each cold boot, setting reverts to Headphones. I expect a setting of Speakers to hold through a reboot, so my system will have working sound on boot-up. $ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04.1 LTS" Upgraded from 11.10. $ apt-cache policy gnome-settings-daemon gnome-settings-daemon: Installed: 3.4.2-0ubuntu0.5 Candidate: 3.4.2-0ubuntu0.5 Version table: *** 3.4.2-0ubuntu0.5 0 500 http://us.archive.ubuntu.com/ubuntu/ precise-updates/main i386 Packages 100 /var/lib/dpkg/status 3.4.1-0ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ precise/main i386 Packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1085552/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
