If you plan to disable the Realtek HD Audio Manager, it is best to do so only after making any necessary sound enhancements or alterations. However, disabling the sound manager may also reduce your system’s ability to alter sound settings (such as equalizational settings) and may reduce your ability to access some sound enhancement options.

The echo should disappear if you're experiencing my problem. Right-click on this item and select Properties. You should see the Line In device in the list. Then, the tab will display in a window with the title 'Sound'. To view this 'Line In' properties tab, right-click on the speaker icon in the notification area, then select Recording Devices (yes, 'Recording'). It was in the 'Line In' properties settings where I had checked off the option to 'Listen to this device.' When I disabled that, the echo disappeared. I also found out a second Line In 'source'. If you want output from the HD Manager, that makes sense. You can open the manager and view the 'Line In' tab - mine had a non-zero playback volume (the slider was NOT all the way to the left for zero playback). The first 'source' I found was the HD Audio manager. I found the problem seems that I was essentially duplicating the Line In audio stream.

I had already set the 'environment' and 'equalizer' sound effects options to, but the echo persisted. My Realtek HD Audio manager seemed to be creating an echo on my 'Line In' audio signal. I just solved my own problem and thought others might benefit, since I could not find the solution using internet search.
