It should be a pretty distinctive click, like a relay clicking. If that's not the cause the amp section of the card may be defective. It should also click when you switch between speakers and headphones.

It doesn't click on start-up. It does click when I switch between speaker and headphones
Rollbacking drivers did not working, going to return it tomorrow for a new one
Edit: never mind I saw it didn't help you.
Perhaps a hardware issue after all

I'm not expecting it to mute the source, some ext volume controllers I've used before had no sound leakage when dial is turned to minimum. It's kind of annoying when you don't want to hear anything at all; makes it more convenient to use an external DAC/Amp.

My old Recon3D USB paired with my Q701, I had to run the USB unit almost at max for adequate volume. With my new Recon3D USB and new K712, I had to turn down PC volume to 20% when the headphone was plugged in directly (no double-amping). I barely used the old Recon3D and Q701 without an amp on PC before, mostly on Xbox 360, but USB is USB, it should have sounded just as loud before, right?!
DJINFERNO, maybe the sensitivity is higher? I believe the Ohms have stayed the same 62, though now it behaves more like I'd expect a 62 ohm headphone to be like. Was listening straight out from my iPod Video (2005) last night, only needed like 45-47% volume setting.
It does not sound as great through the Astro Mixamp. The positioning is alright (DDL), but it just felt so sterile and analytical. I heard everything, but it didn't wow me with musical quality. Unlike on PC where getting absolutely murdered in BF3 (haven't played in some weeks) never sounded so good!
The Sound Blaster Z lives up to a review I read: The Z is more than enough for gaming and is great for music as a secondary function.
