useless sound effect control panel. remove it unless you like your sound to be crappy. Mike Chambers
Realtek Control Panel, can be removed with no danger Goran
Realtek High Definition Driver mostly on HP-machines. It is necessary for the sound and harmless when you install the latest drivers. No virus.  See also: Link Jos
Its a process of Realtech Sounds. Which gives sound effects.  See also: Link Surya
Put in by Realtek audio. Did a clean install of OS and it is one of 2 things in my startup. Not a virus since it was a clean OS. Urtica
Less than a minute after I start up, my mouse won't click on anything, except for the task manager. After I end the "RTHDCPL.exe" process, all is back to normal. Roel

This was taking up 22meg of precious memory on my EEEpc (XP SP3, no page file due to disks being SD ram). Not needed for sound to work. Removed it from startup and added a desktop icon to it for the rare occasion I need to run it. Andrew

My computer was slow and hanging, after I stopped this process from running... Wow big difference! Um
Realtek Audio Manager, can slow down your computer though. Recommend setting the priority as Below Normal in task manager instead of Normal. Jack Yorges
Takes up way to much processing power. A friend
if this file is in c:\windows directory of winxp, it is a duplicate and a malware program. It idled all the processes running on my computer and until I renamed it, I could not get a malware scan to complete. It foiled at least 5 free malware programs by idling them before they could detect the malware. I was able after renaming the file to complete a normal malware scan. ngildelamadrid
Realtek HD audio control panel.
Running the Realtek Audio Manager under Win XP is what's responsible for creating the two dozen or so ".bin" files in your Local Settings Temp folder, one per supported language. really tired
Realtek HD audio control panel. However i crashed it with VST "Massive" and dont know how to fix it now ALfiux
Ad aware does not pick this, nor does virus scanners. This file attaches to sound or video executable's/services and redirects your google search's to random pages. The only way to stop this is to locate the infected service in task manager then search their locations out and delete and replace the actual files with clean one's also make sure before that to stop the startup in msconfig.exe but make sure you activate it once the clean file is in.

This is the Realtek HD Audio Manager Pizza Kitty
I am doing without RDTHCPL in the startup procedures in the HKCU\Software\Microsoft\Windows\CurrentVersion\Run path. Everything about my sound is still running just fine, since I never have a need to change any features of my sound quality. Alexander Moon
I do not use sound very often, and when I stopped the process my internet got faster.
It could be targeted by a virus program so it could become infected, but the file itself is just a driver! YeaHYeaHYeaH
having "weird" gpu usage? As in almost 100% even on the desktop? Delete the file and its all good again... Björn
Realtek HD audio control panel. On my PC happens to hog GPU and VRAM resources, causing overheating. Need to terminate via Task Manager, sound still works fine after termination. MazzoPowah
