Hmm, you did mentioned that a replacement unit also have the same issue, look like there is QC problem somewhere!
Update- Got the latest FW file from Hyundai, updated the Hyundai STB, buzzing sound much improved (still tiny effect hearable, mayb bearable for most ppl), its volume is much louder than NMS (NMS stb vol control like no effect ,adjust + ~ 16 -20 level only can hear like 1 level vol up), I would say Hyundai's support and service is great , at least for my case.
