I have no trouble in receiving 7.1 through my Pioneer amp with the samsung BD -P3600 player, go into audio setings on the player and select bit stream audiophile, by the way i use aan HDMI cable from player to amp.
It work for me, I now receive DTS HD sound & Dolby Digital HD 7.1.
Give it a try.
I must say this is the most disappointing Samsung product I ever have had. I have a Samsung refrigerator. Love it. I have a Samsung monitor. Love it. I have a Samsung DVD player (DVD-1080p7). Works great. So I bought the BD-P3600 because of past experience with Samsung products.
The issue is I CANNOT get 7.1 sound out of it. I have tried the OPTICAL connection. I have tried the COAX connection chained out of my Mitsubishi TV (HDMI from the P3600 to the TV). I have tried the 7.1 analog connection direct to the receiver figuring this is a last resort.
The digital connections will provide the three front channels only (L-C-R) and the analog connection only provides front left& right and surround rear L&R, (NO CENTER CHANNEL AT ALL!!!).
In either case, there is NO subwoofer sound. I used the built in menu option for audio-speaker setup AND the THX optimizer on the MONSTER'S INC. DVD. The DVD player outputs the sound fine, all digital discrete channels, it tests each channel in sequence along with the subwoofer. The bluray player never does. I have tried every combination of option for sound in the menu for BOTH digital and analog (the menu seems to work only for digital, you would figure that there would ALWAYS be 7.1 sound out of the analog outputs). NOTHING I have tried works. I even let it download the latest firmware from the internet (45 minutes on my FIOS connection, they must have one overloaded FTP server)
Has anyone achieved 7.1 sound from their player? The built in sound menu is useless.
My HT Receiver is a Kenwood VR-6070 (THX Surround EX) with an additional PIONEER amplifier for the rear speakers.
