Question: no orange "learning mode" light and bad static

1. if I was unable to get an orange light of any kind (for learning remote commands) is it broken? should I take it back?

2. if speakers are loudly popping static all the time (with or without sound playing) if that's an audio amplifier problem is that my TV or is that the soundbar? how can I fix this?
(btw it's hooked to my tv (LG) with a digital optical to analog converter...in case that affects anything)
