Hi @Klondiked,
A warm welcome to the Roku Community!
We will be more than happy to assist you with your inquiry about the Roku streaming stick or Roku speaker that will be connected directly to your projector. Please be advised that you can get 4K pictures, making Roku a great option to pair with a projector. You can connect a Roku Stick directly to a projector, but to get the sound to a soundbar or speaker system, you should use a wireless HDMI kit and an HDMI audio extractor or A/V Receiver.
Please let us know if there's anything else we can do to help you.
All the best,
John
