Fix for Windows 'AudioDg.exe'
Posted: 13 May, 2012
Is AudioDg.exe overloading your Windows 7 or Vista computer? I mean taking around 25% of total CPU power or loading in a ton of audio latency?
That's what I thought but was wrong. Actually it was some miscellaneous background process under the control of the TaskHost.exe program.
All I had to do was go into Windows Task Manager (right click on the Task Bar, see it then start it), find the TaskHost.exe in the Processes
screen then right click on it and select ‘end process tree’. Problem solved.
It will stay solved until you reboot the machine then TaskHost.exe will start again happily on its housekeeping function.
How I Found It.
I first noticed this problem a few days ago while attempting live HD audio recording with my keyboard virtual instruments. Suddenly notes were
sounding way late and some were getting stuck on. I run Windows 7 with auto updates on and system was completely upt to date. I looked at Task
Manager Performance screeen, which was usually a flat line around 1%, and saw a lot of activity taking about 25% of my 4-core machine. I rebooted
and the phantom activity was gone but started again in just a few minutes. I brought up the Task Manager Processes Window, clicked Show Processes
From All Users button at bottom and expanded the window until I could see them all. Then took a screen shot (Alt-PrtSc), opened up Windows Paint,
and pasted it into a new file (Ctrl-V) and saved it as CpuWithLoad.jpg. I then re-booted and captured the same screen image before the mystery
load started and saved a CpuUnloaded.jpg.
Then I compared the two screen shots and determined that the only difference was that TaskHost.exe was running in the CpuWithLoad screen. So I
killed it as above and the load ceased.
Oh, and prior to the testing I spent hours reading posts on the net about others having this same problem, suspecting AudioDg, and finding no solution.
Later, I noticed that after a while, about 8 minutes, TaskHost autostarted again and the problem was back.
I found that TaskHost was running a Windows Service called MicrosoftAntimalwareService and turned
it off (temporarily) in the Services Manager (ControlPanel -> System and Security -> Administrative Tools -> Services).
I left it in Autostart mode but manually stopped the service (while I was playing and recording).
This stopped the TaskHost interference completely. Now I just have to remember to
turn it back on or re-boot the computer when I'm done. Also, I always disconnect my computer from the Internet
when playing or recording.
Hope this helps you.
