Good news and bad news. My elevation speakers are hooked in to my system. Test tones show they all work. Marantz AV8805 is properly configured to decode Atomos and Auro 3D. JRiver is set to bitstream over HDMI. When I play either an Atomos track or an auro 3D track, the Marantz prepro shows the proper format. All speakers play. I thought I was golden until the sound dropped out for a couple seconds. Then back on. Then dropped out again. It's irregular but frequent. I am playing copied ISO files. I also have the actual discs but gee whiz, reconfiguring my bluray player from SACD playback will be a pain. But, I guess I will do it to narrow down the source of the issue.
J River reports input as: 192KHz (incorrect) 16 bit 8 channel. It should be 96KHz. And, of course, 7.1.4 channels.
The Marantz simply reports the active channels and format (both are correct).
Anyone have any trouble shooting tips?
Thanks, Marcus
