Do you have OMX player enabled in your player settings? Reason I ask, is that random loss of the center channel has been a permanent issue for me when running LibreELEC on a Pi connected to my 7.1 AVR. The only way to fix it, was to disable OMX and only allow MMAL acceleration. I never found that to be satisfactory, as this was not addressing the root cause. My experience was that loss of the center channel was even random for the same title. One moment initiation of playback would be fine, stop and re-start, and center channel gone. Never found a pattern as to what broke or fixed it.
