Ok. Do you have a sense for how many machines that will regress due to this patch? If it is common to set all pins to the wrong value, maybe its the M31EI that is the exception. > But I still wonder why PulseAudio cares the headphone jack state even > though this has only one output at all? When seeing the system as a whole, there can be other outputs on other cards - HDMI, USB etc. If somebody e g plugs a USB headset in it will be simpler for the user if PulseAudio does not also show the unplugged 3.5 mm jack. -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/939161 Title: Hardware not showed in Gnome-Control-Center. - [M31EI Series, Realtek ALC861, Green Headphone Out, Rear] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/939161/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
