[Fire TV Q&A, Help & Troubleshooting] twqwctf:
OK I finally entered a chat session and hopefully they will escalate this issue.

You are now connected to Amazon from Amazon.com

Me: After maybe a day of use (it depends), 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.

Amazon: Hello,.

My name is Varun. I will be glad to assist you.

Me: After maybe a day of use (it depends), 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 like a high-pitched tinny after-effect. (See Youtube Samples provided). It is more noticeable the louder the audio. If I reboot the FireTV, the problem goes away for while.

I created Youtube videos of the issue - playing the Amazon intro video- When he says 'Hello, and Welcome.' you can really hear it. Please check out these samples. This is happening on BOTH of my FireTVs connected to two different TVs. Kindly let me know if this can be fixed. Everything else on the FireTV works fabulous. Normal FireTV firmware updates have been occurring normally. These two Youtube videos I made are older, but same issue still happening today

Amazon: Alright!

Thanks for the information.

I am sorry to hear about the inconvenience. Let's try some troubleshooting to fix this.

Me: See both Youtube videos I created

Amazon: Let's try a factory reset of your device, which can solve intermittent problems.

A factory reset will remove any content you've downloaded to your device. You'll be able to download your Amazon purchases from the Cloud after registering the device again.

Will that be fine?

Me: No

It's happening to BOTH of my FireTVs

A reboot of the FireTV fixes the problem for a while

Please have your engineers look at this.

Amazon: Alright!

factory reset will fix the problem. If that will not work, I will escalate the matter to technical team.

A troubleshooting is needed before creating a ticket to forward the issue to technical team.

Me: I am not factory resetting

That is too inconvient for me

I have TWO Fire TVs

both are having this issue.

You want me to factory reset TWO fire TVs?

Amazon: Let me check it again.

From the Home screen, go to Settings > Display And Sounds > Audio > Dolby Digital Output and make sure Dolby Digital Plus is set to OFF.

Then check if the issue is fixed.

Me: 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).

I tried all audio settings.

Amazon: Alright!

In this case, let me arrange a call for you for real-time troubleshooting.

Please provide me your number and I will arrange a call right now.

Me: Please escalate this to your engineering staff, I cannot be a diagnostic outlet for you.

I am a loyal Amazon customer.

Amazon: Okay.

Me: This is not just happening to me. Here are other people having this issue:
