Having set up the X7, playing with all the options and settings... I can't seem to have proper SBX surround off the usb source. This is something I did not have a problem with the built in Creative Recon 3Di on my Alienware laptop, nor on the Xonar U3.
For example: I'm able to set my Recon 3Di and Xonar U3 to 5.1 speakers, enable THX Tru Studio or Dolby Headphone, and get the test cues to function on headphones without issue. With the X7, once I enable 5.1, it literally switches to speaker mode meaning it will not work on headphones whatsoever. Once I set my X7 to headphones, there is ABSOLUTELY no way to enable 5.1, making SBX absolutely worthless with headphones off USB.
Is this a lack of foresight on the part of Creative, or what? SBX, THX Tru Studio, and Dolby Headphone all need 5.1 enabled to get proper surround decoded into virtual surround. Since the X7 is limited to headphones/2 channel, there is zero way to get proper SBX.
What IS GOING ON, CREATIVE. $400, and can't get this right, when your older tech did this properly? I didn't pay $400 to have a very important gaming function missing through the USB.
I bought the X7 to replace my Mixamp, internal soundcard, AND headphone dac+amp. It's supposed to be an all in one solution, yet I'm gonna have to send my soundcard's THX Tru Studio audio into the X7's analog in and double amp th signal to be able to play my PC games in legit headphone surround. through the X7
What a disaster.
