Hi new to the forum so sorry if this is in wrong place. I have a shuttle sn41g2 connected to a sony davsa30 dvd/amp and its connected using twin phono 2 jack. After a while being on the dvd starts making popping noises through the speakers. I switch off and on and its ok for a bit. There is no spdif on the dvd but there is on my PC. Would getting a converter between the 2 and use optical sort things out. Please help its doing my t*ts in!!!!!!!!!
