IDT audio application.

Causes errors with installation of 16bit programs. Kill this process, and installation is normal.
sttray.exe is the advanced audio drivers running on background, its what asks you choices when you plug things into the mic jack and is always on, its ok to disable it for startup, also this program comes with dell computers specifically
It is related to your sound card. However, you can stop it. Your audio will work ( there are and some situation where people reported audio stoped working, but its just a matter or restart to fix it ). I stoped it like hundreds of times with programs like Gamebooster, there was no harm in doing it.
installed audio drivers and then i get this file.... its safe.
it is not a virus. it is integral to run my HP windows 7 laptop audio. mine stopped working after i installed a music/video converting software. fixed when i did a system restore since I could not find a quick fix online.
Found reference to a file of same name in C:\Windows\Widest~1\FREEQU~1\QUICKA~1.DLL. This appears to be Widestep Software who do keyloggers.
Had a localization error after installing driver. Disabled the audio program (sttray.exe) from msconfig... no more error now... just wanted driver anyways....

Best practices for resolving sttray issues

A clean and tidy computer is the key requirement for avoiding problems with sttray. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the sttray.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
