Yup. Don't use the HDMI(ARC) feature.
i just picked up the AVR-1613 a week ago and have have only one issue so far. every single input i have used runs Dolby digital/dts surround fine. DirecTV, Xbox 360, PS3, streaming Netflix. They all play in Dolby digital/dts. until it comes to sticking a blu-ray disc in....the best i can possibly get with every blu ray i've put in is "STEREO" 2.1. i slap a DVD in....pro logic 2 surround, but put a blu-ray in and all i get is stereo. every. single. time.
i have tried in both my dedicated blu-ray player and my ps3....same results. went into the audio settings for the blu-ray player and it's set to auto. same with the receiver. even have gone into the blu-ray menus just to verify i have some sort of Dolby digital/dts audio selected.
i am really frustrated and have no clue how to fix this issue. i have scoured the manual and have turned up nothing.
the blu-ray model is Sony BDP-S590 and the PS3 is the slim version. and no...no coax...just HDMI connections
it actually is on the blu-ray player that i tried the DVD, but i will try the reset regardless.
