Chromecast

A2D2 Stream works with Google Home speakers, and third party speakers/systems with Chromecast built in.

Chromecast Built-in

Chromecast allows you to stream audio from compatible apps and devices to supported speakers and receivers over your Wi-Fi network.

There are two common Chromecast implementations in use:

Chromecast (Standard)

Standard Chromecast supports streaming to individual speakers. Grouping is managed within the Google Home app rather than directly inside the casting app. Playback performance depends on network stability and speaker firmware.

Chromecast with Speaker Groups

Many Chromecast-enabled speakers support Speaker Groups, allowing you to play audio on multiple speakers at the same time.

Grouping is created and managed in the Google Home app. Once a group has been created, it will appear as a selectable device when casting.

If you want to play audio across multiple speakers simultaneously, they must all support Chromecast and be added to the same Speaker Group in Google Home.

Using Chromecast with A2D2 Stream

A2D2 Stream supports Chromecast-compatible speakers and receivers. It will automatically discover Chromecast devices on the same Wi-Fi network.

To stream audio:

1. Tap the Chromecast icon in the A2D2 app.

2. A list of available Chromecast devices and speaker groups will appear.

3. Select the speaker or group you would like to stream to.

If you have created a Speaker Group in the Google Home app, it will appear as a single selectable device in the A2D2 app.

Important Notes

• All devices must be connected to the same Wi-Fi network.

• Speaker Groups must be created in the Google Home app before they will appear for selection.

• Ensure your Chromecast speakers are running the latest firmware using the Google Home app.

Audio Format

Chromecast supports up to 24-bit / 96kHz audio, depending on the receiving device and network conditions.

Simply open the A2D2 App and select the Chromecast speaker you'd like to listen on from the list of automatically discovered devices. 

Please note, due to the way the Chromecast protocol works, there could be a few seconds latency. You'll know the integration has started as on Google Home speakers, you'll hear a cute 'chirp' from the speaker when A2D2 Stream starts its connection

NOTE: 

Most Wi-Fi speaker systems add a small buffer before playing audio. This means the speaker stores a few seconds of audio in advance, then starts playback. This buffering is intentional and helps prevent:

• Dropouts (audio cutting out)

• Stuttering during brief Wi-Fi interruptions

• Sync issues when playing to multiple speakers at once

Because of this, you may notice a short delay between pressing play and hearing sound. Typical delays are around 4–8 seconds, depending on your network complexity. If you are experiencing higher latency than 4-8 seconds please read our support articles by searching for latency or delayed audio.
