Description Chad Clancy 2018-09-26 21:36:42 UTC 
Application: plasmashell (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.18.0-7-generic x86_64
Distribution: Ubuntu Cosmic Cuttlefish (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
-In "Audio Volume (Win7 Mixer) Settings" under "Advanced" Tab. 
-Changed GP102 HDMI Audio Controller Profile from "Digital Stereo (HDMI) Output" to "Digital Stereo (HDMI 3) Output". 
-One monitor (the one with the Volume Settings window on it) went dark for a moment and recovered.

Based on the title of the window, this may be a problem with the (Win7 Mixer) extension, rather than the bundled Audio Volume Settings manager included with plasma.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
