After installing TvOS 12, apple tv 4k doesn't communicate with my Rotel RAP 1580. No audio is coming out of the AVR. In the apple tv audio and video menu, the Dolby Vision option has disappeared also.
Anyone has an idea of what is going on?

For Dolby Vision, try Reset Video Settings, and run the initial test of capabilities again.

Have HDMI Output as YCbCr (and your TV too for that HDMI port)
Have Match Content﹥On for both options
Does your TV show Dolby Vision detection when applicable?
Ok. i will do that and see what happens. Thank you. I will let you know how it goes.
Glad That worked. It also fixed the Dolby Atmos badge issues I've had in the past.
Just got the response. They say the software update will be up this week. Till then, no appletv!
"Thank you for your email regarding the RAP-1580 While it is not online today, here is a link to our website which should have the v1.88 firmware available for download later this week: http://bwgroupsupport.com/download/software Just a reminder that when you perform the firmware update, you will need to run the same update twice. The first time will load the Main software, and the second time will ensure that the DSP software is up to date. I hope this information is helpful. We apologize for any inconvenience. Kind regards, Ken Bowers & Wilkins"
