My 975 has performed great for the years I've had it. Last evening, I put my "Carpenters singles 1969-1981" SACD in my OPPO UDP-203 and...no sound. OPPO OSD shows "SACD DSD" and "5.1". I've listened to this SACD several times via my OPPO and 975. It's been about a year since I last listened to this SACD and I have made no interconnect changes in the interim. CD's play fine as well as a DVD Audio disc. Anyone out there had no SACD output and subsequently solved the problem?
