I just bought a Sony Receiver - STR-DE685 http://www.crutchfield.com/cgi-bin/S...TRE685&o=m&a=0 and using a sound blaster live x-gamer http://www.americas.creative.com/sup...ic=292&sub=270 with a hoontech dbIII addon http://www.hoontech.com/english/prod...bdb3/info.html I have a ati all in wonder radeon graphics card http://mirror.ati.com/products/pc/aiwradeon/index.html . i connect from the db3 to the receiver using a optical cable. i have tried running win dvd and power dvd and i cant get the receiver to see that it is in Dolby Digital or in DTS. but it does play sound thru the optical cable. Can anyone point me in the right direction or help me??
