Windows 7: BSOD every few days after update KB982018

30 May 2011   #11

Windows 7 Ultimate x86

The crash was blamed on audiodg.exe the Windows interface where 3rd party audio extensions hook in (DSPs etc.)
Which means something Audio-related was responsible for the crash. Did you happen to install anything audio-related before the crash (after the soundtap update)? Ask yourself What was I doing (or better what audio related programs were running) and look for culprits there.
Update all your Audio drivers ( conexant drivers (like cAudioFilterAgent/caudiofilteragent64.exe and SmartAudio/saiicpl.exe) via Toshiba) etc.
and monitor what audio related programs crash your rig.
Report back if anything new comes up.

	Issue a !search over all of physical memory for the current process pointer.
	This will yield at least one MDL which points to it.  Then do another !search
	for each MDL found, this will yield the IRP(s) that point to it, revealing
	which driver is leaking the pages.
	Otherwise, set HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
	Management\TrackLockedPages to a DWORD 1 value and reboot.  Then the system
	will save stack traces so the guilty driver can be easily identified.
	When you enable this flag, if the driver commits the error again you will
	see a different bugcheck - DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS (0xCB) -
	which can identify the offending driver(s).

You see, the thing is I didn't even have soundtap until you told me to update it. I figured maybe the driver was installed by another NHC program so I Installed it in the hopes that it may fix any errors. I really don't care about the program and I'll never use it. If I uninstall it will I have to manually remove the driver?

Also, the only thing I was running which effected sound at the time was Firefox. At least the only thing I was aware I was running. I'll update firefox and the drivers you suggested. Do I use regedit or something else?

EDIT: According to firefox's website, I'm up to date. Would the program necessarily have to be running at the time the crash happened, or could it have been shut down sometime before?

Windows 7 Ultimate x86

Let's say the drivers were running (some drivers are loaded before you even start anything.I couldn't say if you need soundtap or not, I just saw in the crash report that that specific driver was running and in the end was responsible for that crash. If you don't need it, uninstall it. I don't know how comfortable you are, meddling with the registry. So I would suggest REVO uninstaller or Ccleaner to clear out any debris. I don't think it has anything to do with Firefox...Audiodg.exe is more for DSP plugins for special effects so to speak, Echo, reverb, Flanger, Phaser or even Karaoke stuff.
The best would be, go through your startup list in msconfig, uncheck what doesn't need to start with the system and install all the unused programs with aforementioned REVO

Well, it's been over a week and not a single crash since I uninstalled soundtap. Thanks a lot for all of your help!
