@Martin Roos: I also have a HP dv6 and all of the sudden this problem hit me too.
@David Henningsson: See my alsa-info attached since Martin didn't provide one yet. ** Attachment added: "Alsa-info" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/921397/+attachment/3562503/+files/alsa-info.txt.Z9SlWyVx9v -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/921397 Title: Speaker audio channel goes mute after plugging in the headphone Status in “alsa-driver” package in Ubuntu: Triaged Bug description: Speaker audio channel goes mute after plugging in the headphone and unmute after the headphone is plugged out. By consequence there is no sound when trying to listen the sound by headphones. This is a pulseaudio problem and can be circumvent by just editing /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf and commenting the line as here: [Jack_InputDevice] #code = Headphone This will avoid pulseaudio to change profiles when headphone is plugged in. Some people affected by this bug don't get the headphones muted, but only a very low volume, this workaround could help too. But to some computer models this workaround could let the sound play by headphones and speaker by the same time (most people don't desire that). On my computer model ( HP Pavilion DV-4 2080br ) the workaround works well and the sound goes only by the headphone, as expected.
