Thanks Tanner for the update.

What was causing my issue is we didn't put enough padding in the multicast from the inca encoder. As soon as we added 100k of padding results were better with audio sync.  

Do you know if the next gen roku boxes can decode ac3?  


Depends on what you mean by decode. All Roku players support AC3, but only the Ultra 4640 (older version) had the ability to convert other audio into AC3. All other boxes will bitstream AC3 via HDMI (or optical for the boxes that have that). They will also bitstream DTS, but that means you have to be plugged into something that can decode it, such as a soundbar or AVR. Few TVs can handle DTS audio. 
Roku Stick (3600), Ultra (4640), Ultra (4670), Premiere (3920), Insignia 720p Roku TV, Sharp 4K Roku TV, Nvidia Shield, Windows 10 Pro x64 running Serviio and Plex on a wired Gigabit network.
