It sounds like you are just playing a stereo source. The DTS Neo 2.5 setting sounds better because it is designed to take a stereo source and up-mix it to a virtualized 5.1. The Dolby Digital setting will only play whatever audio channels are available in the mix. If the audio is in stereo, it will only play audio out of the front channels. So if you play a lot of stereo content, use the DTS Neo 2.5 setting. You might even try the PCM setting and allow the Beam to perform the audio up-mix.

What model is your TV? What exactly is your source? From what app and device?

Surround sound does not play all the time - it’s an channel. Are you sure the program you’re testing with has something being sent to the surrounds?
disregard that - I just saw DTS works.

Does HDMI setting need to be different to PCM?
