It blows me away that Realtek doesn’t fix this problem. Thx! BTW, I’ve had this problem on various machines for years. Playback Devices Speakers(Realtek High Definition Audio), LG UltraWide(2-NVidia High Definition Audio), Realtek HDMI Output(Realtek High Definition Audio), LG UltraWide(NVidia High Definition Audio)-I run 2 LG 34″ UltraWide Monitors, Realtek Digital Output(Realtek High Definition Audio). I have under Sound Cards 2 NVidia High Definition Audio, NVidia Virtual Audio Device, Man圜am Virtual Microphone. And thinks the company's cheating drivers might finally be fixed, maybe In December 2006, I took RealTek to the woodshed for its cheating. System: AMD FX-8350, 16GB, 4.0GHZ, SSD primary drive, M5A99FX PRO R2.0 (Socket 942) Motherboard. I’m running Windows 10 and haven’t been able to get it running since I put this machine together. I don’t have anything for Realtek in the System Tray. Open Device Manager > go to Sound, video, and game controllers > expand the category > right-click Realtek High Definition Audio > Update driver > Search automatically for driver > Windows 10 will automatically begin updating the latest driver available in the database > Restart the PC to apply changes the problem should now be fixed. I see a DTSAudio Svc running in Services. I do have Realtek High Definition Audio in my Device Manager. I tried everything you’ve outlined and still cannot get it running.
