To be honest I’ve heard about it so much since last summer that I figured I didn’t need to troubleshoot as it was widespread. I only started experiencing it in the last month when I upgraded my Netflix account to 4K and started getting 4K/Atmos mixes.
The conditions to produce are: Netflix, 4K/Atmos stream, Apple TV4K, my 7.2.2 system
The symptom is: Center channel info randomly jumps to the left surround speaker and back to center
I’ve heard with other systems that it jumps to different locations, like a height Speaker, there may be some height involved in mine, but I hear it from the left surround. I’ve also heard people say the ‘dialog’ jumps, which of course makes sense as center is mostly dialog, but I hear other center information (ambience, sound effects) jump as well. I’ve also heard speculation that certain configurations are more susceptible, or maybe that it doesn’t occur with some configurations. So maybe it happens with my 7.2.2 setup, but not with someone else’s 7.2.4 (I don’t remember the specific configs). I should also say I haven’t read about it as much lately, but it’s been reported here and elsewhere often, so some may be rolling their eyes.
I’ll just continue to report it to Netflix as that seems to be the source, but obviously the TV is involved (to be clear I don’t have this issue under any other condition). If I get a chance today I’ll watch the opening of Extraction and see if it always happens in the same place.
: I know there are references to this issue earlier in this thread, but here are a couple external sources. The second link speculates that it happens when the bitrate drops too low. The main reason I held off getting Netflix 4K was the limited bandwidth of my ISP, but I’ve been using a hotspot to stream lately and getting over 25mbps which I hoped would be enough. If this turns out to be the cause, then I guess I’m wasting my money on NF4K.
