It doesn't change at all. The sound settings say that the output is "Headphones" even when they are unplugged.
Yes you are right that my speakers are connected to the gray jack on the backplane. They have always been connected that way and failover between speakers and headphones has worked in previous versions of Ubuntu. Now I changed so that the speakers are on the green jack instead and failover now works correctly. So thanks for that tip. But since plugging them into the gray jack has worked before I still think there is a bug here. -- 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/1521987 Title: Sound is not automatically switched back from headphones to speakers Status in pulseaudio package in Ubuntu: Incomplete Bug description: When plugging in headphones, sound output is correctly switched from speakers (line out) to the headphones. When the headphones are unplugged, sound is NOT automatically switched back to the speakers. This bug started happening on my system after I upgraded from 14.04 to 15.10 so it is a regression. Attached is pulseaudio log of what happens when I plug and unplug my headphones.
