No, dont reencode, this is silly. Video and audio is fine, worked well with any Roku for years.
Just wait till they stop bouncing the cases around between the million “helpful support” people they hired and it actually goes to a developer that knows what an audio codec is and how it was changed in the 10.0 release.
Hopefully it will happen in the next 6 month.
Or it might fall to a “senior principal product manager” that has never heard of ac3 and he will single handedly rule it as obsolete, no more ac3 support.
Can go either way, depending on their recent hires - if it were qualified engineers or bunch of no-ones.
Wait, what i have just described, is a typical huge corporation process, and Roku is modern dynamic startup, so that cannot be!...
