Hi @CFO23,
Thanks for taking your first post here in the Roku Community!
Please note to make sure the correct input is selected on your AVR or Soundbar. Check the volume level and mute settings on your television and the master volume level on the AVR or soundbar. Make sure the mute is OFF and that the volume setting is at an appropriately audible level.
