A browser extension that allows you to cast your tab to any sonos device
Until now, it has not been possible to stream audio directly from youtube or any other platform directly from the browser to a Sonos system. Casttosonos offers a similar experience as the cast to Chromecast feature in chrome browsers.
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. Naturally, there is a delay because you're not playing an audio clip, you are streaming, just like how Chromecast does it. 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.
