Hi Just got a Yammy 440 and am very pleased with it. Today added a sixth speaker to create 6.1. Changed the set up to 6 speakers, did the sound test to ensure all working OK. Next for a test - and to my surprise the amp seems to fail to recognise DD5.1 EX disks. The only one it automatically set to EX was Harry Potter COS. It failed to reconise EX on all the following the following Star Wars AOTC (R1) Blade 2 (R1) Harry Potter (TPS) (R2) Monsters Inc (R1) T2 Ultimate (R1) LOR 2 disk (R1) LOR 4 disk (R1) Seven (R1) It seems to have no problem recognising DTS ES however. I can force the amp into 6.1 mode. When I do that sound comes out of the centre rear but I suspect by doing that it may not be decoding it correctly. Anyone here got a 440 and using 6 speakers. Can you confirm all your EX disks are recognised? Have I got a fault? Thanks in advance.
