Will play media, then loud (max volume) buzzing/feedback noise comes out of nowhere!

[NestHubProb34]

I have a nest hub 2nd gen that has never worked properly, warranty and return are no longer options.  It functions as it should for a short period of time, usually an hour or 2, then music cuts out and MAX volume feedback/buzzing/white noise type sound plays out of nowhere.  Has never failed to scare the %@#! out of me so we just gave up on it.   However, I am back to see if there is any fix.  I am willing to take the whole thing apart if need be.

I already did a factory reset and update and it worked for half a day or so, I thought it was fixed but then when you least expect it, fire alarm!!  I appreciate any ideas or comments, thanks!

Hello NestHubProb34,

Thanks for reaching out.

We're sorry to hear that you're experiencing this with your Google Nest Hub. I also appreciate all the effort trying to resolve this. Could you please provide the cast firmware version of your Google Nest Hub? We'd like to check further what's causing this to happen. 

Check the firmware version of your speaker or display

To check which firmware version you're on, follow these steps:

1. Open the Google Home app .
2. Tap your device's tile.
3. Tap Settings Device information.
4. Under "Technical information," check for Cast firmware: "X.XXX.XXXXX." If the device is on Fuchsia, check for System firmware version: "X.XXXXXXXX.X.XXXXXXX".

Check the version on your Nest display

1.  Swipe up from the bottom of the display screen.
2. Tap Settings About device. You should find your "Cast firmware version."
   • For Nest Hub (1st gen) and Nest Hub Max: If “Fuchsia Version” is also listed, this means your device runs Fuchsia.

Looking forward to your response.

Best,

Princess
