I have a Samsung amp, and the sound fades in and sometimes out. The sound fades in and when sound stops (pausing etc) and start again it fades in again unable to hear the first 10 seconds of sound. I've been unable to fix this for a couple of years, and it's really annoying... I've also noticed that when sound finally comes back, text like: Digital (under HDMI), L.PCM, L, sw, and r pops up but when no sound plays, those disappear... Pease help!
