Here's things people need to understand between converting 5 or 7 channels into 2 channels (for stereo or headphones), and converting 5 or 7 channels into virtual surround into 2 channels.
There's extra procesing being done before the final result of getting the audio to become 2 channels for stereo or headphones.
Basic stereo. Most things, like your TV speakers will take a 5 or 7 channel source, and process that down to the essentials left and right audio. That's it. No extra processing being done. Whatever is to the left or right (regardless of whether it's in front or behind you), get thrown to one channel: left or right.
Virtual surround: Things like Tempest 3D Audio, Dolby Atmos for Headphones, Creative SBX, etc. These will take the 5 or 7 channel source, process that into a virtual processing that will emulate multiple speakers, and THEN process that down into 2 channels for your headphones. So yes, the end result is 2 channels, but the sound was processed to emulate multiple speakers.
So yes, just because someone says USB = 2 channels, doesn''t mean it's basic stereo. In the terms of Sony's Tempest 3D Audio, of course it's sending 2 channels to something like the Creative G6. Tempest 3D audio already converted the 5/7 channel source down to 2 channel before sending it to the Creative G6.
The only downside of 2 channel through USB for the G6 is that you won't be able to get the proper SBX experience, since SBX requires 5/7 channels to work properly (which SBX turns into processed 2 channel). This is why you want the G6 to get the optical output of your TV or receiver (as long as they are sending Dolby Digital) into the optical input of the G6.
If you're using Sony Tempest, you don't need SBX, if you're using SBX, you don't need Tempest 3D audio. And you definitely do not want to use both at the same time.
AT NO POINT IN ANY METHOD WILL YOUR HEADPHONES EVER GET 5 OR 7 CHANNELS, UNLESS YOUR HEADPHONE IS TRUE SURROUND, WHICH SUCKS.
