A:Answer Hello, Fred! Most of the improvements have come with the automatic OS updates. Roku OS 12.0 is currently in the process of rolling out to all Roku devices. To verify your streaming device is up to date, you can go to Settings > System > About to check the software version. If you want to enhance your audio experience, a Roku Wireless Subwoofer and a set of Roku Wireless Speakers pair nicely with your existing Roku Streambar. - Happy Streaming!
