A:Answer Hello,
Yes. After the Echo is set up, make sure that your Chromebook has bluetooth enabled.
Then, ask Alexa "Alexa, connect to bluetooth".
Alexa will say "searching" and then once Alexa detects your bluetooth from your Chromebook, Alexa will say "connecting to _(blank's)_ Chromebook".
When you want Alex to stop playing music from the Chromebook, you tell Alexa "disconnect from Bluetooth."
Alexa will acknowledge the request.
