I'm trying to use Dolby sound with my fire TV stick and it says function is not available. Anyone else have trouble with the fire tv stick?

Is it any certain type of Dolby? Please provide the full model code so that we can best assist.

Neither Dolby or Dolby+ are available. Here's the model info, thanks for any help you can give:

Are you using Dolby with the stock speakers? It is generally meant for external speakers with more range.
