Google Cast-enabled site vs. casting a tab's audio — Google Cast device

Some websites are Google Cast-enabled to deliver the best possible entertainment experience. Currently, Google Play Music, iHeartRadio,   Plex,are Google Cast-enabled and we're adding more Google Cast-enabled sites all the time!

How will you know if a website is Google Cast-enabled?
You'll see the Inactive cast extension Cast icon on the website within the music player. For sites that are not Google Cast-enabled, you can use the Cast extension to view the audio content using your Google Cast audio device.
Google Cast-enabled benefits

On sites that are Google Cast-enabled, there are numerous benefits to using controls provided by the site instead of just casting the tab's audio for that site. These include:

  • Higher quality: Google Cast-enabled sites can serve high quality content that is best for listening on audio device. This will often mean you'll get a higher bitrate audio or improved content.
  • Battery life and computer load: Google Cast-enabled sites play directly on a Google Cast audio device, and put no load on your computer. Casting a tab's audio requires a lot of your computer's power, which is why it's not supported on all computers.
  • Plays independently: When you play from a Google Cast-enabled site, you can shut down your computer or close the lid. With tab projection, you will need to keep your computer on throughout the cast.

Google Cast-enabled sites will generally try to automatically switch from casting a tab's audio to an optimised mode of operation if you are already casting a tab's audio when you visit the site.

Casting a tab's audio is still very useful for sites that aren't Google Cast-enabled, but whenever you see the Cast icon in the video player of a site, that should be your first choice!
