Audio Ducking in Windows 7 - disabled but still occuring

Hello!

I've searched through these forums and have located the proper settings to disable to stop audio ducking from occurring when loading Teamspeak, Ventrilo or Mumble. The Windows 7 menu says "Do Nothing" like in the following screenshot/post - System Sounds Auto Leveling - Disable . I've also gone into Mumble and disabled attenuation and have gone into Ventrilo and done the same. I still get the audio volume lower when any voicecomm software is active.

Any ideas? I've checked the Realtek control panel and don't see anything there that could be doing it, either. I've been in the guild wars 2 settings and don't see anything there, either. Starting to drive me a little nuts that it keeps happening even though I've told it to not.

Thank you for your help!

Hallelujah!

I stumbled across the solution. Posting it to a number of places as I've seen others on other boards trying to hunt this down.

I think it has to do with Realtek audio driver behavior. This worked and stopped my system from audio ducking (even when "DO NOTHING" was selected in the communications tab):

Right click on your volume control, then pick your playback devices tab. Right click on your speakers, then choose "Enhancements". In the scroll bar area, check "Loudness Equalization". My system stopped audio ducking.

Audio ducking is a "feature" of Windows where when the OS detects an incoming communication-type action it lowers (or "ducks") the sound of everything else by a percentage. So, when in Ventrilo/Skype/Mumble, etc, in-game sounds will lower itself.

Audio guys call it "ducking". :)
