-To hear audio, you need a TV, AV receiver, or soundbar that can decode Dolby Digital or AC3 audio over HDMI. Most modern TVs can do this, though we’ve noticed a few Samsung TVs cannot. All Roku televisions should be able to play audio without any trouble.+Some Roku models pass the audio through to the television to decode. This is supported by almost all televisions but must be configured on the Roku and/or Television.

-  * To receive most ATSC 3.0 broadcasts you will need a Roku device that supports the AC-4 audio codec, such as a recent Roku TV set, or the 2020 Roku Ultra or later (but not the "LT" version). If you do not have a Roku TV set or Roku Ultra that supports AC-4, we would recommend using an inexpensive "Google TV" device with your TV set, instead of buying a new Roku Ultra, as Google TV devices tend to be less expensive and have less issues with live TV. Please open a support ticket for the latest information and advice regarding AC-4 support: **[[:Support ticket]]** +  * The following models support ATSC 3.0 content:
