Hi all, I'm having a bit on an issue with my Sony AVR. When Blu-Ray is connected via HDMI the amp plays Dolby digital or whatever the disk wants no problem. However, when a video source is connected, I goes immediately to Linear PCM and I can't get Dolby back at all. It's strange that the output can have a HDMI lead connected but as soon as the TV/projector is turned on, it switches from Dolby to PCM. Any ideas please guys? I'm running out of them. Thanks!
