Thanks for your bug report. Is the machine you are using a desktop? If so, then at the moment, this is by design. There have been discussions in the development community about how we could allow the user to choose what is muted etc when plugging in headphones etc to different ports on the machine, like what is possible in Windows, but there is nothing decided yet.
If however this machine is a laptop, then this is certainly a bug. If you could let me know what type of machine it is, then I may be able to give you something to try to fix the problem. Thanks again. ** Changed in: alsa-driver (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/785830 Title: [HP Compaq dc7900 Convertible Minitower, Analog Devices AD1884A, Black Headphone Out, Front] No automute -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
