What is rthdcpl.exe?
Rthdcpl.exe is part of Realtek HD Audio Control Panel. It is installed along with the drivers for Realtek sound cards and audio devices and allows you to modify the settings of your Realtek audio device.

This process is an nonessential system process; however, it should not be disabled unless absolutely necessary. Disabling or uninstalling the Realtek HD Audio Control Panel may leave your system without sound. If it is causing problems, however, uninstalling it will not have any other ill effects on your system.

Dangers of rthdcpl
As this is a relatively common process that runs on most systems with a Realtek sound card, 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 but be stored somewhere other than in %SystemRoot%. Other malware may use a name that appears similar to it 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 this file in an incorrect location or with a slightly different name.

There is typically 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, the presence of this process may indicate that your system is infected.
