Vior PDP42V18HA 42 "plasma TV speakers are making a crackling noise?

is that the TV itself? I have to plug it manually mono to stereo, mono and it makes a popping sound. I can not get it to stay in stereo. Does anyone know anything about this? but I hae called the company, were not of much help.

because they are going wrong or you have been growing the TV volume too high.
