multiple instances of ravbg64.exe

After browsing my processes through my task manager I've found that I have about 5 instances of the same RAVBg64.exe running at the same time. I know that at least one of these are legit but I am not sure of the others. Also many of my steam games have started to have massive frame drops. Are these additional files viruses?

Sunbro

That process is your realtek.  I would install the newest driver available even if it is the same date becuase drivers do become corrupt

There are quite a few threads with issues in that driver.

RAVBg64**.exe, Realtek HD Audio Background Process, ... that RtkNGUI64.exe is eating up 13% of my Core i7-2720 2.2Ghz system.**

    It appears to be starting multiple instances of the program with different command line switches.

    I have three instances running, and here's partial printout of relevant entries from registry key

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]

    "RtHDVBg_Dolby"=""C:\Program Files\Realtek\Audio\HDA\RAVBg64.exe" /FORPCEE4"

    "RtHDVBg_LENOVO_MICPKEY"=""C:\Program Files\Realtek\Audio\HDA\RAVBg64.exe" /LENOVO_MICPKEY"

    "RtHDVBg_LENOVO_DOLBYDRAGON"=""C:\Program Files\Realtek\Audio\HDA\RAVBg64.exe" /LENOVO_DOLBYDRAGON"

    BTW, to avoid confusion (because this was originally posted as a Windows 7 problem, this computer is Lenovo Yoga 2 Pro running Windows 10 Version 1511 Build 10586.14. So the multiple instance behavior of this driver program seems to have been similar for a long time.

    Hope this helps, Bob

    Hi Mark,

    To assist you with your concern, you need to check your manufacturer's website or contact them for the updated drivers as suggested by ZigZag3143").

    Let us know how it goes.
