Multi-room group playback FAQs

Group creation

Do I need all of the speakers to be on the same network in order to group them?

Yes. To successfully group the speakers, you will need to connect all of them to the same network.
Note: Dual-band access points (5 GHz and 2.4 GHz channels), wired connection (Ethernet), and connection through Wi-Fi extenders are all supported with group playback.
Make sure to disable Access Point (AP) or Client isolation on your AP or Extender, and that Multicast forwarding is not disabled between the Wi-Fi networks.
How many groups can I create?
You can create as many groups as you want.
How many speakers can I add to a group?
You can add as many speakers to a group as you want. However, when you add too many speakers to a group, it might lead to increased network congestion and a higher chance of audio dropouts.
Can one speaker be part of several groups?
Yes. A speaker can be part of as many groups as you want.

Playback quality

Is the audio being resampled or altered?

How can I avoid dropouts during group playback?
In order to ensure reliable group playback, consider the following recommendations:
  • Try to connect with at least one Chromecast Audio using the Ethernet Adapter for Chromecast.
  • Try to connect with Chromecast Audios that are close to your router to a 5 GHz network.
  • Try to place your Chromecast Audio closer to your router.

My group of speakers is consistently playing out of sync. What should I do?

One of your speakers might be adding some delay to the playback. Try to adjust the group playback delay for that speaker.
I've cast to a single speaker of a group during group playback and the group playback stopped. Is that expected?
Yes. When you cast to a single speaker of a group during group playback, the group playback will stop on all speakers.

Adding or deleting groups

Can I add or remove speakers to an active group playback?
You can add speakers to the group during playback by editing the group. Note: When you remove speakers from an active group, it will cause the playback to stop.
My group card isn’t showing all the speakers that I’ve added to a group. What’s wrong?

First, check that all group speakers are plugged into power and connected to the internet. Then fully close the Google Home app and reopen it. 

If you’re still unable to find your speaker(s), this article may help troubleshoot the issue. 
I deleted a group and it keeps coming back to my Devices list. How do I remove it completely?
Sometimes, it will take a minute for the group to be completely removed from the Devices list. Please delete the group again, wait 1-2 minutes, and then fully close the app and reopen it.
Note: Speaker group creation is only available on a phone or tablet. This feature is not supported on the Chrome browser. However, you can still cast to a group from Chrome.
