With both the optical audio out and ARC HDMI all channels will create a popping sound
Deno DHT-S514 Soundbar
LG 75UK6570AUA TV
With all installed applications (Hulu, Amazon, etc) an intermittent popping sound will occur with the soundbar that increases with frequency over time and becomes rhythmic. The problem occurs with both optical audio output and HDMI ARC connections. The odd thing is it is not consistent and begins at random times. This does not occur when the television's speakers are being used and appears to be isolated to the soundbar.
Any ideas on why this could be occurring?
