For OMNI BAR+, three sources are available: HDMI (not applicable for ADAPT+), Optical or AUX input. For Adapt+ two sources are available: Optical in/outputs and Analog in/outputs. If you select "Watching movies and TV shows" in the HK controller app for either one of them, you will have a very little delay and good lip sync with the TV for video applications. However, you will not be able to rebroadcast the TV signal to other OMNI+ speakers when selecting this mode. If you select "Listening to music", you will be able to rebroadcast TV signal to other OMNI+ speakers in your house, however, you will have lip sync delay with video material. Select that specific mode if you use HDMI (not applicable for ADAPT+), Optical or AUX for music only. Using Chromecast, Spotify Connect or Bluetooth is not part of these modes. When using one of these streaming methods, you are able to rebroadcast any music source.
