Something strange is happening. I have a Sony S6500 player and have had no issues with decoding DTS-HD or DolbyTrueHD from it in the 17 months I've owned it, but a couple of nights ago it stopped decoding the HD signal and defaulted to DTS and Dolby Digital. No settings had been changed in the player and I also hooked up an old half-knackered Samsung player to my Yamaha RX-V677 receiver to see if it may be at fault, but the Samsung player played the HD soundtrack via the amp without any issue. I also tried different HDMI cables and HDMI sockets but nothing changed. I assumed the HD decoder in the Sony player must be faulty so today I went and bought a Sony S3700 to replace it. After the set-up process had finished, which included a software update, I popped in Hacksaw Ridge and hit play, and once again the player wasn't decoding the HD signal. Could Sony have possibly stopped supporting HD audio? I have exhausted all troubleshooting that I can think of so I thought I'd hand it over to you fine people for some advice?
