I just got the xg1v4 to use with my Weatinghouse 4k TV. I am using standard stereo mode as I don't have a 5.1 sound system yet. I am getting audio drops for 1 to 2 seconds every 10 to 15 seconds. I spent 3 or 4 hours looking on the internet for an answer. Many people have the same issue. Whether using stereo mode, 5.1 or fiber. After many hours I saw a comment about secret user mode for box. 30 minutes later I found a comment with no description or comment, but a list of remote strokes. I have a Motorola system, but tried it anyway. On your remote press and hold the Xfinity button for 5 seconds ( I did it for 10 seconds). Then press the down button twice and then press the number 2. After 3 seconds I got a new system menu. I did not change any parameters, nut went through every option, including diagnostics. After walking through each option my glitching issue stopped. This is the right solution.
