Part of the SoundMAX drivers, completely harmless. Enables the customized volume control in the tray.
smtray.exe is a installed with Sound cards with ADI chipsets. This process merely places an icon on the system tray for easy access to SoundMAX diagnostic features. This is a non-essential process. Disabling or enabling it is down to user preference.
SoundMAX tray icon, not dangerous, can be safely disabled.

Best practices for resolving SMTray issues

A clean and tidy computer is the key requirement for avoiding problems with SMTray. 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 SMTray.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.
