Roku Device Features, Settings & Updates

Help configuring Roku device settings, using Roku OS features such as screen mirroring, adjusting display type and audio settings, using Guest Mode, and assistance with software updates.

Hello all, I have a projector with HDMI available. I tried the Roku Streaming Stick + (3810, 3811 series) and the video worked, but not audio. Can I leverage Roku devices to capture the audio? What will work? Roku Streambar or Roku Smart Soundbar or Roku TV Wireless Speakers or other device?
