What is alcxmntr.exe?
Alcxmntr.exe, or the Realtek AC97 Audio Event Monitor, is a service installed with Realtek audio drivers. It is not known exactly what this program does; however, it is a necessary part of the Realtek drivers.

This process is not essential to the operation of the system; however, you should not make any attempt to disable it. Doing so may prevent your audio from working.

Dangers of alcxmntr
As this is a program that runs on most systems with a Realtek sound card or integrated audio, it is possible for virus writers and spyware vendors to disguise their malware as the genuine one.

Some malicious files may have the same name as this but be stored somewhere other than in %SystemRoot%\System32 or %SystemRoot%. Other malware may use a name that appears similar to that of the legitimate one but with slight differences in spelling or with appended digits. While there are currently no known viruses, Trojans, or adware applications that disguise themselves as this process, you should look out for the presence of this file in an incorrect location or with a slightly different name.

There will typically be only one instance of this process running at a given time on a system. The presence of multiple instances may be an indicator of a malware infection. If you do not have a Realtek sound card or a motherboard with integrated Realtek sound and you see this process, your system may be infected with malware.

Common problems
  • This process uses 100% CPU time
    • This is an isolated problem with the Realtek audio drivers. Ensure that you have the latest drivers. If you already have the most recent drivers installed, try reinstalling them.
  • This process prevents Windows from shutting down properly.
    • This is a very uncommon problem that occurs only in isolated cases. Try reinstalling your audio drivers and ensuring that you are using the most recent ones.
