            Bug ID: 101674
           Summary: "Dummy Sound" when headphones removed after wake from
                    sleep
           Product: PulseAudio
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: daemon

I have been able to reproduce the following bug in both Ubuntu 17.04 and
Manjaro 17.0.2 on a 2017 Dell Inspiron 15 5567. It uses RealTek audio codec
ALC3246. If you plug in headphones, then put the laptop into sleep mode by
shutting the lid, then open the lid again, audio hardware will cease to be
detected and be replaced with "Dummy Output". Booting into another operating
system, or booting onto a live USB will not fix this problem. However, if I
take apart the back and unplug the CMOS battery to reset the NVRAM, audio will
be immediately restored on reboot. I have been able to reproduce this and
recover from it 100% of the time in both Manjaro and Ubuntu, running XFCE with
the most up to date version of Pulse Audio.
