Bad cables are something that should always be checked first ... also, many people do not push the HDMI end into the jack all the way.
HDMI cable is different than an Ethernet cable ... HDMI is a slender narrow metal end, which carries audio and video , while the Ethernet cable has a smaller box type end, usually plastic with a lock tab on it, which locks in place and should be pressed first before trying to pull out of the jack. .... Ethernet cable carries the Internet/Network feed.
Many Ethernet cables go bad from people just yanking them out.
After a few months of intermittent attempts to rectify my audio problems (dropping audio for a second or two every few seconds) I found a fix for my system. I turned my audio output in the settings for my fire cube to stereo output and let my reciever up convert the audio signal to surround sound. I believe that the first issue was my cube outputting a 7.1 surround sound and my reciever was trying to reconvert the signal... essentially bottlenecking the signal. As soon as I changed the setting of output the sound became flawless. Hope this helps!
I think I’ve found a fix for this issue. It’s had me stumped for ages but I figured it out last night and hope it works for you guys too. My setup is a Samsung 3D tv hooked up to a pioneer vsx 2020. The firestick is 4K. My amp has a signal select function where you can switch the signal from optical, hdmi or automatic. I switched this from automatic to hdmi so it stayed in hdmi all the time. I then set the firestick sound setting from best match to Dolby digital plus. When the amp was on automatic and the sound setting in the firestick was set to best match, the audio drop out would cause the amp to search for the next available input with a sound signal. The problem with the firestick is that it’s just a platform so relies on content for sound signals and codecs to send to your amp, so when you go to YouTube or prime, the silence will cause a drop out. Amazon techs can fix this by making the firestick send a permanent inaudible sound or codec signal to the amp so it doesn’t drop out.
This may (or may not) be completely unrelated... I have an Toshiba 4K Amazon FireTV. A few days ago, shows on Netflix and Netflix alone starting having a pop followed by a short period of silence. Sometimes it is rare enough that the show is still watchable(ish) but other times I just miss too much dialog. The strangest thing is that I also have a Roku 3 connected to an HDMI port on this TV (so that I can use the Spectrum TV app that is not supported on Amazon Fire devices) and I get the exact same thing using the Netflix app through the Roku. All of my sound comes out of the TV into a Bose Solo speaker. The Amazon app, Pandora, my in-home Plex server and the Roku's USB media player all produce good quality sound. ONLY Netflix has an issue and it seems to be something to do with the audio output from Netflix as perceived by the FireTV device.
I also have a TCL 4K Roku TV, and another Roku 3 on an LG TV (with an external Sony sound system that receives all audio from the LG TV) and Netflix works just fine on them, just as it does on my computer in a web browser. So only the Fire devices seem to have a problem with Netflix audio output.
I really hope Netflix and Amazon stop pointing fingers, telling users to factory reset, etc. and just fix the damn thing. Personally, I believe that Amazon doesn't want to conform to something Netflix is using that all other systems handle and I also believe that Netflix is doing something potentially unique that is probably not really necessary and Amazon doesn't think it should bother with it for just one service (especially their biggest competitor in streaming video.) Finally, since these two are competitors in the stream video market, I don't really see either bothering to fix anything -- customers be damned. I know I will never buy another Fire device. I only have this one because as a 50" 4K TV, the price was too good to ignore at the time -- next time I *WILL* ignore it in favor of a Roku TV because I have helped several friends an family get those set up and never had a single issue with them and they run more things than the Fire does -- at least things that I know about.
So, Amazon & Netflix, if either of you is listening to this: Please prove me wrong. Show that your customers matter by agreeing to get this stupid issue fixed. It seems to have existed for a very long time. Haven't your customers suffered with it long enough?
I have been having audio cut outs with my 4K Firestick. My audio cuts out much longer that just a couple of seconds, in fact it does not seem to return. After 20-30 seconds of no audio, I stop waiting. The only remedy for me has been to restart the Firestick, sometimes two or three times over a few hours of viewing. I did not experience this issue at all during the first 4 months of ownership. Now it happens everytime I watch a show and usually about 30-45 minutes in to viewing. I have switched the audio setting to "stereo" as many users have suggested. But I am still experiencing the problem.
I had the same dropouts issue on the Fire stick From prime day 2019, switched to a different HDMI port and works fine. On an older Toshiba tv 40FT1U from 2010 with optical to a jvc receiver from the tv. It only does stereo via pass thru , but no dropouts. Much better than a dropout every thirty seconds.
they are back, every minute to minute and a half on my 100 mbps connection. I couldn't even play prime music without the dropouts!
Having the same issue. I had an older 4K Firestick which was plugged into my receiver which was then connected to my Samsung 4K tv. Never had any issues. We recently moved and I bought a new Samsung 4K tv and plugged the Firestick directly into that. That's when I started experiencing the audio dropout. At first I thought it was the tv, but when I went to other TV functions, the speakers were putting out sound. Purchased the newer 4K Firestick and it's doing the same thing. For us, the audio just drops out and we have to restart the Firestick to get the audio back.
No idea why the older Firestick was working perfectly fine in our previous setup before moving but started dropping audio after we moved and connected it to a new TV.
