Minix Neo X8H Plus with firmware 004 Playing back: MKV's Issue: At certain points throughout the movie you hear loud digital squealing for 1-2 seconds. It then returns to normal audio, and a bit later will do it again. Tested the same files before the 004 upgrade and they did not do it. Tested the same files on another Neo X8H Plus with firmware 003 and it did not do it. Players are connected to a Denon receiver. Thanks!
