7.1 Surround Sound Effects off of DTS HD Master & Dolby True HD lost?

[Gravion2005]

HI all. Ok i put my PS3 on Linear PCM, then i put my Onkyo905 on DIRECT. Do u guys know that only the left and right speakers with the base box worked. I have a 7.1 surround sound hookup and i put on the FLY & everything was just in LOUD increments in the front speakers only. I heard NO kind of SWISH or sound running around the 7.1 speakers at all. I was SO disappointed since i heard how HD Master, lossless & dbly True are supposed to be the BEST. Then when i took it off, switched the ps3 to bitstream then put it on thx Neural 7.1, THEN i heard it around the speakers. What gives? Did i do something wrong? Y have a 7.1 surround, or even a 5.1 Surround if u can't hear it SWISH and awe u cause it's only coming out of the front 2 speakers? How can that be the best?
