Mixxx freezes when unplugging monitor

[Thomas]

I am running:
Mixxx 1.11.0 x64 on Windows 7 Home Premium x64
Intel i3 2.4ghz with 8gig ram
System Audio: Realtek High Definition Audio
HDMI Audio: Intel(R) Display Audio

Problem:
Mixxx crashes when a hdmi monitor is removed while a deck is playing. This does not happen if there is no music playing.
Note that the htmi audio port is never used, and is never selected as an output in mixxx.
Also, under audio settings, I have Primary Sound Device selected as output, not the system specific device. This will not happen if I select a specific device as the output device.

Example:
I have a HTMI monitor that has audio outputs on it(because it is htmi). When that gets connected or disconnected during the mixxx runtime, mixxx crashes. Same with my usb speekers, and usb sound card.

Additional:
If I change any of the hardware while mixxx is not running, mixxx will warn me on the next run that there is no output device selected in the output tab, and sure enough, there are no aduio devices selected for any of the outputs or inputs(they are in the lists though).

Yeah this is a well-known and hard problem to fix. For now all I can say is "don't do that."

Hm, I'm afraid this looks like a bug in ig4icd64.dll (your graphics driver):

ig4icd64!ShCompile
  ig4icd64!DllMain
  ig4icd64!DllMain
  ig4icd64!DllMain
  ig4icd64!DrvSwapBuffers
  OPENGL32!wglSwapBuffers
  GDI32!SwapBuffers
  QtOpenGL4!QGLContext::swapBuffers

Looks like you removed the monitor right in the middle of Mixxx issuing a command to the graphics driver. I can only guess that the driver didn't like that and crashed. :-/ can't think of anything in Mixxx that we could fix here.
