So here is a clarification that I should have done when reported the bug...
Unespected behavior: When plugging the headphone, speakers AND headphone output goes muted. Expected behavior: Only speakers goes muted, but not headphone output. After plugging headphones there should be sound at the headphones. More details: After plugging the headphone, at alsamixer the Speaker volume control gets muted (only this control) and it's volume goes to level zero: 0 <> 0 If I manually unmute Speaker volume at alsamixer, it's volume still at level zero and there is no sound to headphones. If I level UP the Speaker volume level I get sound to headphones and no sound at the speakers (wich is the expected behavior). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/921397 Title: Speaker audio channel goes mute after plugging in the headphone To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/921397/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
