I have a QIP 6416-2 HD DVR connected to my Samsung 4k TV with HDMI.
I have seen audio dropout problems mentioned in the forums going as far back as 2008 but nothing very recent. I am having two specific problems:
1. Occasional lowering of volume without user input to cause it which usually lasts about 15-20 seconds.
2. And most annoying, are audio dropouts which last long enough for a word or single syllable of dialogue to be completely missed. This happens at random times and may occur as many as 100 times during a 1 hr broadcast. It will happen whether I am watching a broadcast or DVR playback BUT does not reoccur if I "rewind" my program a few seconds and replay the where it happened before. This tells me that the problem is not in transmission and must be in the STB. Incidentally, I had this same problem with a formerly used Sony Bravia TV.
With years of forum complaints and alleged "fixes" to refer to I have tried them all without any luck. I have:
-changed out the HDMI cord.
-routed the STB HDMI cord to a different TV input.
-accessed the "hidden menu" > additional HDMI settings > and changed to L-PCM.
-accessed the FIOS menu > Settings > Audio & Video > Audio > Dynamic Range & selected None.
-on the same page accessed Volume Control and alternated between Fixed & variable.
-accessed Audio format and alternated between stereo and surround.
-and probably a few other suggested fixes that I've forgotten over time.
I have two other STB's in my home, one SD and the other HD(non-DVR). I do not have this problem on those other boxes.
This kind of problem or something similar is mentioned hundreds of time in these forums over at least 6 years. Hasn't FIOS come up with a fix yet? Can anyone help, please?
This is maddening enough to cause me to consider going back to Comcast, God help me.
