A browser extension that allows you to cast your tab to any sonos device

Quick Answers
Is there a free version?
Yes – the Free plan lets you stream in standard mono quality with unlimited time.
Do I need extra software?
No. Only the Chrome extension is required. Nothing additional runs on your system.
Will it slow down my browser?
Streaming is lightweight. Performance impact is minimal on modern machines.
Is there audio delay?
Sonos speakers buffer audio internally (a few seconds). The extension compensates so video stays aligned even though playback starts slightly later.
Why are my videos laggy?
This can be a side-effect of the video-sync feature on very large screens or older devices. To disable this feature, follow the following steps: - Right click on the extension icon - Click on "Options" - Enable the checkbox next to "Disable video sync" - Press the "Save" button
What quality levels are available?
Free (mono 128 kbps), Stereo (192 kbps), Premium (320 kbps).
Can I use it on multiple Sonos speakers?
Yes, higher tier plans allow selecting groups / multiple speakers for synchronized playback.
Does it work offline?
You need an active network connection; streaming relies on Chrome and your local network to reach Sonos devices.
How do updates work?
Chrome automatically updates the extension. You'll always receive the latest improvements once published.
Why do my invoices say 'Echo Sierra Studio' on them?
I'm unable to register a seperate organization with our payment providers. This is a temporary compromise and may change in the future.
After installing you can easily cast any audio clips that you can play inside chrome, to your Sonos device by going to the top-right and clicking the puzzle icon.
After opening the extension, you can make a choice to use the free version with limited quality or the premium version. After that, you can select the room and the group you want to cast to. The selection box will become selected and the play button will show up after the extension is connected to your device.
If you are not able to connect, make sure that no other app is using your Sonos device, Spotify or Youtube for example. Try pausing or disconnecting from the app that is currently using your Sonos device.
If you are experiencing technical issues, you can go to the Chrome Web Store "Support page" and leave your questions there and we will get back to you as soon as possible.
Technical note about the delay
This extension streams your audio from your tab to your Sonos device. While there was previously a delay because you're streaming rather than playing an audio clip (similar to Chromecast), this problem has now been mitigated by synchronizing the video with the audio delay. The advantage is that it works for every website and with any kind of audio source that Google Chrome supports.
With this extension, you are not able to turn your Sonos device into PC speakers. You are better off buying a good pair of normal PC speakers.
