Discovery+ does not list their supported audio formats. As of 2021-12-03 all their content is streamed in only stereo with no surround-sound support (AC3/5.1/etc). I suspect they do not disclose this because it is a major negative to those who expect at least 5.1 audio on a modern streaming platform. I have verified it is only stereo with Discovery+ support, directly. And several threads on Reddit also confirm this, such as: https://www.reddit.com/r/ShieldAndroidTV/comments/kqa5uy/discovery_plus/ or https://www.reddit.com/r/cordcutters/comments/kzaa8c/discovery_good_and_bad/ However, I have been unable to find any review or authoritative source to cite. Citing Reddit or my own confirmation is not adequate. Just because it is un-cited does not make it untrue or less valuable to point out to those who are looking for information about Discovery+.
As such, I tagged the information provided under the "Criticism" section with a "citation needed", but it would be best to leave this valid information in the article until someone can either prove or disprove it with a citation.
This is the exact Email from the Discovery+ support team:
