Windows XP guest crash, null audio driver involved => Fixed in SVN

Reported by: mhanor Owned by:
Priority: major Component: audio
Version: VirtualBox 3.2.2 Keywords: null audio driver XP guest crash
Cc: Guest type: Windows
Host type: Windows

Description

host OS: Windows XP SP3 32 bit
guest OS: Windows XP SP3 32 bit, fully updated, including the latest version of Silverlight (available on Microsoft Update)

Guest options that are not required: NX, VT-X, 2D, 3D ,USB, network, guest additions
Required: Null Audio Driver ICH AC97. Selecting the host's sound card will not trigger the guest crash

The BSOD occurs within 10-20 seconds after clicking the Webcam/Mic tab, available at the Microsoft Silverlight Configuration utility (Start -> All Programs -> Microsoft Silverlight -> Microsoft Silverlight). This program hangs after clicking that tab.
I can reproduce it every time. The BSOD parameters are different every time, almost like it's memory corruption.

yep, 3.2.4 does it too, with a fresh install of the guest OS

comment:2 Changed 4 years ago by mhanor

if GA are installed, it takes more than 10 minutes for the guest OS to crash... like before, the crashes occur at different points, with different codes every time

  • Summary changed from Windows XP guest crash, null audio driver involved to Windows XP guest crash, null audio driver involved => Fixed in SVN

We believe we found the problem. The fix will be included in the next maintenance release.

Incidentally, if installing Guest Additions made (or seemed to make) any difference, it was entirely coincidental. The audio emulation was indeed corrupting guest memory, with rather unpredictable results. The guest would always crash, but how and when was more or less random.
