            Bug ID: 90972
           Summary: No sound when plugging in headphones, must unmute and
                    raise Speker+LO to get sound
           Product: PulseAudio
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: alsa
          Assignee: pulseaudio-bugs at lists.freedesktop.org

Recently (month back or so) I've discovered that headphone jack handling has
started to misbehave:

Whenever I plug in my headphone jack:
* The Master slider is changed to a stored value specific to headphones
* The Headphone slider is unmuted and set to 100
* The Speaker+LO slider is muted and set to 0

And there is no sound output from the headphones, only if I unmute and increase
the volume of Speaker+LO do I get output in the headphones, this is something I
need to re-do each time plugging in headphones.

I've attached alsa-info and amixer output with and without headphones.

I originally believed this to be the same as
https://bugs.freedesktop.org/show_bug.cgi?id=90491 forwarded to
https://bugzilla.kernel.org/show_bug.cgi?id=99681 but after some discussion
there it was concluded that this was likely a pulseaudio issue instead.
