Synchronize

Creates a sync-group from any number of specified players (they must all be on the same LMS server).

Specify the master player first in your list, followed swiftly by the slaves.

This works best if you just list the names in flow, without long pauses which will cause Alexa to assume you're finished listing things.

In general, specifying lists to Alexa is error prone and any humming and hawing will likely cause errors. The skill does try to match only player names from your utterance and will list any spurious words being rejected as an invalid player.

You can say 'synchronize everything / all players / all my players' to automatically group all the players attached to the same server with a simple command. If you get a 502 error while doing this it means one of your known players is disconnected — just perform a player discovery to remove it and try again.

Invocation options (choose based on grammar-fit):

Alexa, [ open / start / launch ] MediaServer
Alexa, [ ask / tell ] MediaServer [ to / for ] …
