Roku Ultra LT and HDHomeRun - No audio on ATSC 1.0 or 3.0

Hi!

Thanks for the suggestion.  I don't have "leveling" or "night" on.  Instead it's "off".

I should be at least be able to get the ATSC 1.0 to work.

It's my understanding HDHomeRun processes the sound in the cloud, so that it does work with more devices.  The issue may be that Roku limits the app to certain specifications which limits what HDHomeRun can do? 

This Roku Ultra LT purchased at Black Friday price of only $30 packs a lot of punch with its REPLACEABLE BATTERY remote (why rechargbeable on the Ultra (not LT)when someone can opt to buy rechargeable batteries?--that is THE reason I did NOT buy that and now I can't since the sale price is no long valid), voice remote, direct connect headphones through bluetooth (no app or remote needed), easy to navigate uncluttered interface, ethernet port, etc.  I mean Apple doesn't include ethernet except on their highest priced new model.

Is there any way this might work later when I do replace the TVs?  I was hoping not to do that until they actually broke.

A paid licensed codec should have never been used for "free" TV broadcast.  It increases the price of equipment needed, requires some equipment to be replaced, etc.  I realize that is not Roku's fault, but I'd be willing to have paid more if it requires different hardware or for a reasonably priced software update to the model I have if that's an option.  Can this be fixed through software?  Somehow HDHomeRun has addressed this through their app for more compatibility because you still cannot watch these channels through the free alternatives (plex-has paid option too), Jellyfin, etc.) due to this codec.
