Chromecast Audio Group Bluetooth Speaker (inverse) delay

FreezerMan2001

I bought a whole bunch of JBL speakers with Chromecast and already have a Nest Mini bluetoothed to a speaker. I put them all in an audio group to play music throughout the house. 

The issue is the Nest Mini bluetoothed is actually QUICKER than the other speakers. By approximately 500ms (making the 200ms delay function useless). Everyone else has the exact opposite issue. It's even quicker than the Google Home Mini was - that synced fine when not bluetoothed. 

Things I have tried to remedy this:

  • Move the Nest Mini further away from the bluetooth speaker
  • Change bluetooth developer settings on both the speaker and Nest Mini (from my phone)
  • Transmit bluetooth audio to the speaker from one of the JBLs
  • Change to a bluetooth USB dongle
  • Literally none of the above worked, in fact when I transmitted from the JBL it actually created a major delay, so the typical issue everyone else is having. That was fine, except the delay was >200ms so it is the exact same problem just inverted. 

Any tips here apart from chucking it all in and moving to Sonos?

I don't have an answer. In fact, I'm hon here looking to solve the exact same issue. The Nest Mini syncs up fine but when I try to use my JBL Charge 4 its ahead. I'm hoping for both of our sanity that someone with answers chimes in here.

Hey folks,

 

I’m sorry for the trouble this has caused you, let me help you out.

 

Make sure your devices are connected to the same network and within 15-20 feet of your router. Give these steps a whirl:

 

Recommended: Group delay correction adjustments should only be made while music is casting to the group. This adjustment allows the customer to immediately hear the changes they made.

 

  1. Cast music to the group that plays out of sync.
  2. Stand between the out-of-sync speakers (or as close to in between as the customer can) and adjust their volume levels so they hear them both play at about the same level.
  3. Open the Google Home app.
  4. On the home screen, tap the Chromecast Audio device where the customer wants to correct group playback delay.
  5. Under Device features, tap Audio > Group delay correction.
  6. Move the slider to the left or right until the audio sound is in sync.

Let us know if the steps help!

 

Thanks,

Alex

What you suggested was to use the group delay correction. 

In my original post I said:


The issue is the Nest Mini bluetoothed is actually QUICKER than the other speakers. By approximately 500ms (making the 200ms delay function useless)


So what you suggested is completely redundant.

Hey FreezerMan2001,

 

Sorry for the confusion.

 

Have you tried deleting all the speaker group that you have and created a new one? Also, try resetting your Google Nest Mini.

 

Best,

Alex

Hi Alex,

Thanks for your response. Here are the things I have tried to solve this:

  • Resetting the Home Mini
  • Creating a new speaker group - many times, many variations
  • Playing purely through the Home Mini without bluetooth (syncs perfectly)
  • Playing to the same bluetooth speaker from a JBL Link Music (syncs slower - opposite problem)
  • Moving the home mini further away
  • Restarting the router (many times)
  • Upgrading all firmware on everything
  • Joined dev programme

Nothing has worked thus far.

Hey FreezerMan2001,

 

Thanks for doing all those steps. Since it's only happening when you pair your Home Mini to your JBL speaker, is there a way to reset your JBL speaker as well? This might also be related to the latest update about speaker group that if it contains non-Google speakers or Cast-based devices may not work properly in speaker groups.

 

Kind regards,

Alex

Hey FreezerMan2001,

 

I wanted to follow up and see if you are still in need of any help. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.


Best,

Hi Azarco,

There seems to be some misunderstanding, the issue happens when I pair the Home Mini to my bluetooth speaker. 

If I pair a different JBL Music to the same bluetooth speaker (JBL Music acts as the home assistant, using the bluetooth speaker as the 'Default music speaker') then the issue inverses. That is, there is now a delay on that connection in the speaker group.

Hey FreezerMan2001,

 

I understand. To make sure they are on the updated version, resetting your Bluetooth speaker might help. 

 

Thanks,

Alex

Hi Azarco,

I have reset all devices many times, still no difference. All firmware upgrades have been done.
