A:Answer Bluetooth or Chromecast Audio feature can be used, as long as your project supports it. Also, keep in mind, if you choose connection other than HDMI, you WILL LOSE the ability to decode and playback high definition audio format, like Dolby TrueHD, Dolby Atmos, DTS X etc. In addition, depending on the version of Bluetooth version on your project, you may experience video and audio out of sync issue. The bottom line is, it is recommended to use HDMI connection as possible.
