Crank does have the 6.1 PCM option, in the manual sound setup on my ps3 there is no option for 6.1 linear PCM only 5.1, 7.1. as well as Dolby 5.1 and DTS 5.1, I also have every box checked. What was strange, when I played Crank and used the Square button to show the info, the ps3 was sending a 7.1 LPCM signal to my receiver.
And thanks for the other info. now I don't have to worry why the display on the receiver doesn't act the same as when an optical signal is going in.

A computer once beat me at chess, but it was no match for me at kick boxing.
