What do you guys think of Creative Omni? Worth trying? I heard good things about SBX Pro.
I recently bought the Xonar X3 and absolutely loved Dolby Headphones. I'd set the number of audio channels to 6 (5.1) Turn on Dolby Headphone (dh1) and set surround in BF4....sounded great. I loved it so much I decided to upgrade to U7....It arrived today and here is what I found:
Dolby Home Theatre and the U7 in general seems to be crippled to 2 channel audio when in Headphone Mode. This renders Dolby Headphones into more of a stereo expander rather than a 5.1/7.1 virtualizer like it was in the U3 and the older sound cards. The newer internal sound cards seems to have fallen into the same sad shape. I have no idea why this was done but you can read these links and see for yourself that Asus is aware of it but hasn't made any indication that it will ever be changed.

So as of right now it seems that my upgrade wasn't much of an upgrade if I want to continue using Dolby Headphones....as a matter of fact I think it was actually a downgrade.
I'll keep fiddling with things.....if any one has different info I'd love to hear it.
Thanks in advance!
Dolby Theater is exactly the same, it just does it behind of what u see, it activates Shifter 7.1 automatically and 5.1 surround, I tried to test 7.1 speakers but it doesn't work. in games u can feel the differences and don't use Surround in BF4. use Hi-Fi and Stereo. Surround is if you use real 5.1 or 7.1 not virtual. That's what I heard from people and it does sound better as I played more with Stereo.
Hi Thanks for the reply.
I just received the U7 so as I have time I'll try to get it setup so that Dolby Theater's Dolby Headphone sounds like it did on my U3.
I just can't get over the fact that Windows shows it as only being 2 channel audio when in Headphone mode.....are you sure it switches on 5.1 in the background somehow? If you don't mind me asking, where did you get that info from?
I'll try using Stereo Mode instead of Surround in BF4....but that doesn't seem right. How can Dolby Headphones know what to put in the right rear channel if it is only being fed 2 channel (left/right) audio? I would think Dolby Headphones would need to be fed the discrete 6 audio channels (5.1) in order to downmix/virtualize that info into 2 channel stereo....but I'm not an expert....
I just can't get over the feeling that U7/Dolby Theater has castrated Dolby Headphones by feeding it only 2 channel audio.....hopefully I am wrong.
Hi all,
I had a little conversation with Dolby last year regarding this issue. Please check:
Me:
As a long time user of Dolby Headphone technology from Asus Xonar soundcards, I am concerned that the new Dolby® Home Theater v4 headphone implementation found on the Xonar U7 might be inferior to the classical Dolby Headphone. Please clarify that for me.
Thanks Peter
Hi Peter
I apologize for the delay in responding to your email, the team was attending E3 last week. The algorithms between Dolby Headphone and Dolby Home Theater v4 for headphone virtualization are the same, so there shouldn’t be any difference. You may be hearing a difference because DHT v4 features things like volume leveling, dialogue enhancement, etc.
I hope this helps. Best

Hi again,
here comes the next question. This is a big discussion on HeadFi.org. When DHT v4 is activated for headphone use, does Windows or the running application send real 5.1 or 7.1 to the sound processor ? Or does it only provide stereo information that is kind of processed to sound like surround. So is it real multi-channel information or only stereo the basis for what DHT v4 sends to the headphone? That is very important for a lot of FPS gamers out on HeadFi.org and elsewhere. And the new interface tells us nothing about what’s going on behind the curtain…
Please clarify
Peter
Hi Peter,
Thanks for the email. In Dolby Home Theater v4 the headphone virtualizer algorithm receives and processes discrete multichannel audio. Hope this helps. -

For me the the issue is solved, because it works audible. It works in games like COD, Battlefield Bad Company 2 and Crysis 3, and in movies like The Matrix. Only that Windows shows 2 speakers only makes us all worry.... but as I said it works perfectly. I also have the Xonar U1 which uses the old interface with DH and all that stuff. Windows shows up to 8 speaker when I use it, but the effects are the same as on the U7, only that the U7 sounds better overall.
If you need stereo, you can disable Dolby completely.

Hi Harvester,
Honestly, I don't think there should be any sound quality differences (others than effects used for gaming) between the regular U7 and the Echelon version of U7, mostly because hardware is exactly the same and ASUS specs looks identical on paper. So, if your original U7 has some background noise on headphones, then this might be caused by your sound source or by ASUS software or defective drivers. I'm only using the U7 for music and while listening, I always make sure that Dolby and ASUS control panel software are closed and all sound options are OFF (there should be a Hi-Fi setting in ASUS control panel). For testing background noise I always use sensitive 32ohms like AKG 550 or IEMs and trust me: U7 has no background noise at all (at max. gain and max. volume!).
Besides the external aspect, I believe the only difference between the 2 cards would be the firmware; that's why when I was trying to install Echelon drivers & software on U7 didn't let me.
If you're able to take some inside screenshots and post'em here would be great. Also, if you can find some pictures with internal components of Echelon on Internet, please let us know. This way we can find out if there really should be any differences between U7 and Echelon, besides the ASUS software included in the package.
Regards!
Hi Folks,
I'm planning to buy this (apparently) wonderful piece of hardware. However, I was wondering if the following is possible? I'd like to set the u7 up like this:
PC -> U7 -> 5.1 system (via optical/coax)
-> Headphone via front (ill plug them in only when using)
Now, as far as i know, the u7 will automatically switch to the headphone setting when connecting a pair of headphones? Can I configurate the u7 so that, when I have no headphones attached, the u7 outputs dolby digital live over optical/coax to my sound system and then when I plug in my headphones, it switches to Dolby Headphone? And in reverse ofcourse, when I remove the headphones?
I hope my situation is clear, thanks in advance for any insights =)
