Getting sound routed through a soundbar instead of your TV's built-in speakers is usually a short, one-time setup.
Most home setups route a streaming device's audio through the TV, and then out to a soundbar — rather than connecting the streaming device to the soundbar directly.
Check your TV's audio output settings first — it's common for a TV to keep playing through its own speakers even with a soundbar connected until this is changed manually.
This is a separate, common issue with its own fix — see our guide on fixing audio that's out of sync while streaming.
