My Ultra is connected to a Denon X3300 AVR, which is setup to pass through the video signal to a Vizio M70-D3 4K display (the Denon handles the audio, obviously). All devices are connected using Monoprice certified 18Gbps HDMI cables. I also have a Sony X-800 UHD player connected through the Denon AVR to the same input on the Vizio display, which plays all content perfectly fine.
The HDCP errors would occur when I would first attempt to play actual 4K HDR content from Amazon (the only app I use on the Ultra for this type of content). This issue only occurred with a certain version of firmware on the Ultra, and no longer occurs.
The wireless disconnects can happen randomly at any time using the Ultra -- but have not occurred when I am actually watching something, but only when navigating within or between apps. The only way to correct the issue is to unplug the Roku, reboot my wireless router, and then power up the Roku. This issue has only started happening since the last firmware update -- I think the FW date is 9/25/17. I have at least 10 other wireless devices which never have issues and continue to function when this happens - including devices in the same equipment rack.
The audio issues have evolved over time. They started with random audio chirps when watching Amazon or Vudu. Those were eventually fixed via a firmware update, but replaced with extremely high volume levels to the point of distortion. Another FW update appears to have eliminated the distortion, but the volume level is still way higher than it used to be -- much higher than my other components (I have a Panny BD player, Oppo DVD player, and Xfinity cable box connected to the Denon, as well as the previously mentioned UHD player and Ultra). I compensated for this by lowering the input level on the HDMI port on my Denon -- the first time I have ever needed to do this with any component or AVR.
As I've stated before, each of these issues would arise immediately after a Roku FW update, and some were corrected immediately after another FW update -- only to be replaced with another issue. With the number of issues that have occurred immediately after a FW update, the only logical conclusion is faulty firmware. Once or twice may be a coincidence, but not four times.
I was skeptical of the issues others were reporting with the Ultra at one time, too, as my unit was very stable for the first several months I owned it. It's just been in the past few months that things have turned to crap with all the firmware updates.
