OK, here's the deal according to TC's tech folks. The best I could get them to commit to was a "[based on the currently available updates, these models work best]" as far as Roku players go. They are:
-Roku Express (latest models)
-Roku Ultra
-Roku Premiere+
Premiere+ are not currently available on roku.com, but the Express and Ultra are. I asked about the currently available Stick and Streambar models, but they did not specifically recommend them. I think it's worth considering that app and platform development teams are constantly addressing compatibility issues and pushing updates. However, they have to pick their battles. TC subscribers who own older/certain Roku players (I own 6) may not draw a lot of water, so to speak.
They did reiterate what Customer Service told me over-the-phone which was that Fire TV Stick and Apple TV devices "generally" are not experiencing this audio sync issue on live broadcasts. Of course, one of them could always push an update that results in more or less devices working properly. Getting everything to work properly across all these platforms is always an ongoing process.
For my part, I'm impressed with Tennis Channel's phone and online support and will probably return as subscriber once I pick up a couple of new Roku's.
