You can mute the headphones by pressing the marked button

Please add an option in "Output" to mute the RCA output because when I listen via Headphone my Loudspeakers are playing the music too.

That's helpful to mute the headphones, though muting the speakers is far more important, since that's what would bother other people. The UI does make it seem like the speakers can be muted, but doing so also mutes the headphones also (clicking the headphone mute to apparently unmute it doesn't do anything). So as far as I can tell, there's no way to turn the headphones on and the speakers off in the software.

We will provide the option to mute both the line out and headphone out separately in an upcoming software update.

That's awesome! If you had the ability to assign a hot-key to toggle between headphone and speaker, I would be in heaven!

Hello!  Just installed my new EVGA Nu Audio card and so far so good.  Had a bit of a snafu with the molex to sata connector, but a quick forum search cleared that up.
 
On topic - I switched from the ASUS Xonar STX II, and I really liked the fact that you could switch outputs.  Seems to me that both RCA and the headphone out are tied together somehow at a hardware level.  Or muting one or the other wouldn't be a solution.  I could just turn off my speakers if I wanted that.  Anyway, they had some cool software that let you do that and I would love to see that in a future update.
 
On a technical note - is there a reason mute is the answer here?  Are the outputs tied together via the same amp?  I am not an engineer, but I had thought that the headphone out was different from the RCA out.  Therefore, it always made sense to me on my Xonar that I would have to switch between the two audio outputs on the sound card.  And when you did, you could hear the click, like I hear from my receiver when switching between speaker outputs.

Sorry, I've missed that.  It's my first day with the new sound card.  But I am still curious - are they tied together?  Or are they independent outs?

So, I found that the software switch is indeed a "fix," but the system volume slider doesn't adjust headphone volume which is kinda disappointing.  It would be nice to have a feature where, when front panel audio is plugged in, the speakers are disabled and the system audio slider changes headphone volume.
 
For example, if I have my headset connected to front panel audio, I have to alt-tab to change the volume on it rather than use the wheel on my keyboard (which manipulates the system volume).

Although the recommended method of using the volume is to max the Windows volume slider first, then adjust headphone volume, I think you can make a slight exception for that sort of situation.  Drop the Windows volume down to roughly 67%-85% and find a good volume with the headphone slider.  Then just adjust the Windows volume while you're in an app or game.
 
The headphone slider cannot be directly controlled by the Windows Volume slider, because the headphone volume in the software directly controls the independent analog volume controller.  However, we are looking to add the ability in a future update to create hotkeys to control it without having to leave an app or game. 
 
To make sure you understand the various volume options, though, the "Master Volume" simply turns the Windows volume up or down; it's not tied directly to the line-out.  Instead, the Master Volume will affect line-out, headphone out, and front panel headphone out.  However, the mute button under the Master Volume is directly tied to the line-out and will enable/disable the line-out at a hardware level.  Otherwise, the headphone volume is tied to the headphone analog volume controller, as well as the mute button.
