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.

This thread is rather old, but I will say that the HDHR works just fine on my Ultra 4800. This of course isn't the same model as the Ultra LT (there are two different versions of Ultra LT, the 4662 and the 4801). 

As a test I went to the den and tried it on my Ultra 4670. On that device I too had no audio, neither the ATSC 1.0 or 3.0 stations. 

This problem is all on Silicon Dust. There's nothing Roku can do to resolve it. I remember shortly after I bought my HDHR Flex 4K Silicon Dust stated publicly they weren't making much of an effort on the Roku platform. I don't know the reason for it, but it might be because only the Ultra 480x models support AC4 audio, which is what ATSC 3.0 uses. It could be that they have simply make their app no longer work for any other model of Roku. But that is a Silicon Dust decision, not Roku. And Roku has no power to make them do anything differently. 

I just read a post on the SD forum, and there is a licensing issue with ATSC 3.0 stations. Some stations are turning on DRM, and they are making it difficult for SD products to view ATSC 3.0 stations that have done so. I wouldn't think that would impact it working on ATSC 1.0 stations, but there's certainly a problem right now. 

No.  I ended up buying a Roku Ultra when they went on sale this past Thanksgiving.  I have audio now with ATSC 3.0 and 1.0.  Most of the ATSC 3.0 are encrypted now, so I can no longer get those stations until the drm issue is resolved.
