While streaming audio is more specifically tailored for mobile phones and tablets, your VSSL can still stream music from your computer or laptop.
Currently, Apple only supports streaming to a single zone of audio via AirPlay 2 from your MacBook. Simply enter the sound controls and change the output of your device from Internal Speakers to the VSSL zone of your choice.
You can also cast your computer audio from a Mac, Windows, or Chrome OS system by utilizing Google's Google Chrome browser.
Ensure your computer and VSSL unit are on the same wireless network. Go to the music streaming website of your choice using Chrome. Click a song, album, or playlist. Click Play. If you’ve pinned the Cast button to your toolbar, click the Cast button in the Chrome toolbar (upper right corner) of your browser. Otherwise, navigate to the Chrome Settings menu in the Chrome toolbar located at the upper right corner of your browser and click “Cast..”.
Next to where it says, Cast to …, you’ll see a small dropdown menu where you can select your custom Google Speaker Group(s).
