This may be more of a Kodi issue, than a CoreELEC issue.
Now that the ATSC 3 TV broadcast standard, is being implemented in the United States and in a couple of other countries, they have selected Dolby AC 4 as the audio codec that will be streaming.
Is there any future plans to be able to use that audio codec using the PVR add-on?
Right now when I tune an ATSC 3 channel, I have a great video but obviously no audio, since that audio codec is not supported at this time.
