Uses typically 10% CPU when no audio is being used. If killed in task manager, it immediately starts again, thus impossible to stop. File modification date (3rd Feb 2015) is before the file creation date (11 Mar 2015) ??!!

If I end this process in task manager it restarts immediately. This seems to be a new behaviour. It used to stay ended. It uses about 5% cpu even when I have no audio i/o.

it uses like 0.5% cpu
type "sc stop audiosrv" in the command prompt. there, no more audio dg.
Malwarebytes detected it as a Trojan.FakeMS
On my system, the audiodg keeps trying to 'inject code' into other processes (a function windows allows for trusted programs, as with reading memory of other programs and many other security holes, although it is probably as designed, although also used illegally by the security state)
Use a ****load of ram but isn't dangerous

Best practices for resolving audiodg issues

A clean and tidy computer is the key requirement for avoiding problems with audiodg. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the audiodg.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
