I've encountered a new glitch today.
I had been using ARC to get DD+ audio from the TV's apps to my AVR. Today, out of the blue, it stopped working. I have only the one input to the TV--HDMI 3 (ARC) from the AVR's Monitor1 (ARC) connector. As of today it stopped conveying audio. I've tried all the standard troubleshooting steps I could think of (and then some) to no avail: double-checked all the audio settings on both devices; reseated the HDMI cable; tried a different HDMI cable; turned BRAVIA Sync off and then back on; turned ARC off and then back on in the AVR; rebooted TV and AVR (both hot-boot and cold-boot), etc., etc.
I ran a digital optical (Toslink) cable and changed the TV audio input on the AVR to digital and am getting audio from the TV once again without the use of ARC. But, of course, this means no DD+ and no Atmos.
The one thing that I noticed is that in the BRAVIA Sync Device List there is a duplicate entry labelled "ADI Repeater" that I don't recall ever having seen before, and I wonder whether this is an indication of the hangup. The list looks like this now:
Device Input Audio System Type
Device 3 HDMI 3 AVR-X8500H
Audio System HDMI 3 ADI Repeater
My last resort would be to perform a factory reset of the TV, but I am naturally loath to do that since I would lose all of my custom settings and calibrations. I tried calling Sony customer support with the typically unhelpful results.
I will keep troubleshooting, but in the meantime I would appreciate any suggestions anyone here might care to offer. Thanks.
