Bad Bluetooth Audio(low pitch).

[ToyasDhake]

I have been using my Nest Hub (2nd Gen) for more than a year now with my Samsung HW-T415 as a Bluetooth speaker. Everything was working fine till today afternoon when my Nest Hub got updated and suddenly the Bluetooth is not working properly. I connect to the speaker but the audio is weird it is slightly low pitch than it is supposed to be and there is a significant lag while playing and pausing anything. 

I already tried resetting the Hub and the speaker. It did not fix the issue. 

Does anyone have any idea? Or is there a way to revert the Hub to the previous version?

Hi ToyasDhake,

This is not the experience we want you to have, let me help you. A few questions: when you did the reset, was it the same steps as what you see in this link? Is the audio issue happening on your Samsung HW-T415 only when connected to your Nest Hub (2nd Gen) via Bluetooth? Could you confirm if it’s also happening on your Nest Hub (2nd Gen) by unpairing both of them and playing only on your Nest device?

Looking forward to your response.

Best,

Dan

Hi Dan,

Thank you for replying. Yes, I followed those steps. The audio from the soundbar is normal when it is connected to my Android phone via Bluetooth. The audio directly from Nest Hub (2nd Gen) after unpairing is also normal without any lag.

I think have narrowed it down further. So the audio is good when the soundbar is connected to my Android Phone and also when it is connected to my Linux laptop. I can check the Audio sample rate on my laptop and my phone, it detects it as 44.1kHz. When I connect it to my Windows 11 laptop it detects it as 48.0kHz which results in the low pitch laggy behavior. I was able to replicate the bad behavior on my Linux Laptop by forcing it to use 48.0kHz.

In conclusion, either the support for the 44.1kHz sample rate was depreciated in the new update of Nest Hub  (2nd Gen) or there is a bug in the update which is resulting in the selection of the wrong sample rate.

Dan, is there an update on this issue?

I have been using my nest hub and Samsung bud+ for about a year, every was working well but in the last few weeks there has been a lag in audio and intermittent Bluetooth disconnects. The same audio is fine when using the hubs speakers and the buds work fine when connected to my mobile. I also noticed that the motion sense does not seem to recognise movement when I enter the room, which it always has previously

I have reset the hub and paired and un-paired the buds from it without any improvement.

From the sounds of it, I'm assuming this has started due to a recent update.

Please can you help

Hey AlanG1,

Can you connect the buds to your phone and check what biterate is the phone using? If it is 44.1 kHz then it is exact same issue I am having (Nest hub not detecting correct bit rate). You can check it in settings under developer options of your phone. 

[AlanG1]

Hi, yep it is 44.1kHz. are you, or were you on the preview of the home assistant?

I was on the preview when this started but have since reverted. But I did read somewhere that the version is still active until there has been another update

[ToyasDhake]

Sorry I didn't get you, home assistant? I just have the Nest Hub connected to the soundbar via Bluetooth.

Hello folks,

Thanks for the additional info you've provided. Could you please provide the cast firmware version of your Google Nest speakers?

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

1. Open the Google Home app .
2. Touch and hold 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 for your responses.

Best,

Princess
