New FireTV, unrooted, running software version 51.1.4.1_user_514013920. Running SPMC 13.3.3.

After maybe a day of use, the audio on the FireTV develops an high-pitched 'whistle' effect. It's not a constant whistle. It only accompanies the sound you are hearing. It is more noticeable the louder the audio. If I reboot the FireTV, the problem goes away for while. It affects all audio system-wide including SPMC (I spend most time in SPMC, don't use Amazon apps much yet).

FireTV audio set to 'Dolby Digital Plus Off' but happens no matter what FireTV audio setting is. If I unplug HDMI and plug back in, problem persists. Rebooting FireTV fixes it (until the next day when it recurs).

Youtube video of the issue - playing the Amazon intro video- When he says 'Hello, and Welcome.' you can really hear it.

Is anyone else having this issue? I exchanged another FireTV at the store because I thought the device was defective, but here it is happening again. What is going on here. :(

I can NOT hear any distortion at all on the youtube vid you link. Sounds fine to me. I turned the volume up and turned off anything making noise. Sorry I'm not of any help.

There is this high pitched whistle sound. It's obvious. When he says "Hello, and Welcome" for example, the high pitched whistle is very clearly heard.\

You know, it's not 'distortion'. I chose the wrong word. It's a high pitched whistle sound. That's the best I can describe it. My 12-year old walked in and noticed it. I know it's not just me LOL.

I'm sorry, it's not obvious to me. Have you tried taking your AFTV to a neighbors/friends house and seeing if it has the same problem on their TV? This way you can rule out your TV as the cause. Another thing to try is a different HDMI cable.

How can it be my TV or HDMI cable if I unplug the FireTV then plug it back in (reboot it) and the problem goes away? It is an old TV (from 2003 I think), I'll give you that.

(What I need to do (tomorrow) is record another Youtube video (A vs. B) so the difference can be clearly distinguished. I'll post again tomorrow )

It's about finding what the problem is. By using a different TV, you can rule out if it's an AFTV problem, or possibly your TV. You said you returned another AFTV for the same problem already, and 2 of them have the same problem, which isn't common, and you getting both? Not very likely.

So if we rule out the TV and can rule out the HDMI, then it leaves that you got very unlucky and got 2 AFTV's that ended up with the same problem.

And do you happen to hear the sound loudest when you have a mostly white screen?

I hadn't noticed a correlation between whites in the screen and the audio anomaly. I'll have to go back tomorrow and inspect further. I hear your suggestions about ruling out the TV and cable. I have another cable so I will try that very soon. I also have another TV- I will try that one also. I will update this thread as I find out. Thank you kindly!!

I don't have a fire TV but it sounds like a crappy HDMI cable. Try a different brand then what you are using. I had got some cheap HDMI cables from amazon and this happened to me with one of my bluray players and a computer.

I have a gold tipped Vizio HDMI cable that I got from Wal-Mart at an inexpensive price.
I've never had any problems with it at all.

Look for a gold tipped one with 4K support like my Vizio HDMI cable.
Even when FTV is max 1080P,it helps tons that the HDMI cable supports an even higher resolution.

I'm going to troubleshoot with a different HDMI cable. However, it is confusing to me how a reboot of the FireTV would resolve the audio issue completely (for a while) with the same HDMI cable. Can a low-quality HDMI cable degrade or become corrupt during it's connection to the display over time?

i'd agree, but you should still try, maybe its the TV, when the FireTV sends different audio sources with like different bitrates or number of channels or something to your TV its somehow borking or mis interpreting the signal.. doesnt happen all the time because there could be something in some video content somewhere at some point triggering it to mess up.. but you would think a TV reset would fix it.. did you try unplugging the TV and just leaving the fireTV running and seeing what happens when you power the TV back up?

It could be electrical noise. Try a different outlet / circuit and see if that helps. It also could be noise / interference picked up in the HDMI cable.

<<did you try unplugging the TV and just leaving the fireTV running and seeing what happens when you power the TV back up?>>

Haven't tried that. Will do and update this thread. It will take some time as the problem re-appears after about a day.. Thanks!!

The Vizio HDMI cable was my replacement for a cheap nickel-plated GE HDMI cable that had major issues such as Slenderman static randomly appearing.

Words Of Advice:Make sure to always go for gold-plated HDMI cables,avoiding the cheap nickel-plated ones.

I see the problem. It would drive me mad as well.

I have a cheap long hdmi cable. I highly doubt that will make a difference. Bestbuy always sells the gold plated one. As for the sound, test it directly to the TV. Are you going through a processor. I had mine go through the bose lifestyle 535 and I got a lot of distortion and I thought something was wrong with the firetv. Who would think anything would be wrong with bose. Eventually it turned out the bose got defective and bose changed the processor under warranty and the flicker is totally gone.

Try it direct on the TV and see what happens. if not try it on another tv and try isolating the problem one at a time. Test other hdmi cables as well.

The FTV is connected directly to my old Panasonic TH-37PX50U (from 2004 I think). I'm still waiting for the audio whistling problem to recur again today.

does it happen with other sources? if not It may be the audio sync. If it still does not fix, then try hdmi to RC

If you still have issues, try researching on converting the hdmi to analog with left right maybe? something like the one below. since the tv is old, it may not be able to handle the hdmi signals correctly.?

I had an older 2nd gen AppleTV connected to the same TV earlier. No issues there. I used that AppleTV for several years. Still waiting for the audio issue to happen again today..

the noise may come back. did you change out your hdmi cable. If it still happens. try the hdmi to component and see if it goes away. If you have a video processor like the bose or something else that may help too.
