It seems like it has been fixed on my TCL TV with 10.0 for me, thought it’s hard to say if there’s not still some delay.
Can anyone else (@Insomnic_1 ?) help confirm?

Yeah! Roku OS 10.0 on TCL seems like it fixed it for me (updated 5/13). My test file was egregious and it seems in-sync now.
Thanks @emichael for calling it out. I get the “is there still delay?” question but can’t tell if it’s just me being used to looking for it or not. Worse case I flip back to the non-direct play which wasn’t impacting any of my playback anyways.
Since the 10.0 update, I’m having audio dropout issues every 10-15 seconds that are driving me nuts! I’ve tried changing the various passthrough audio settings around, all same result including stereo. The sync does indeed look fine but the audio dropouts are almost equally as annoying. I even tried doing a factory reset last night but same issue persists. Anyone else having this at all or know anything else for me to try?

I haven’t experienced that myself but I only have the one TV and it’s hooked to a soundbar - it might be useful to start a new thread on it and get some dedicated testing from others (these older audio issue threads are mostly dead now).
I did have to redo my remote options to control the TV (dedicated remote) after update - but I would think you doing a factory reset would clear any of those types of oddities for your sound setup.
I’m having the same issue. One thing got fixed, another got broken.
I started a thread for this new bug on the Roku forums.

I haven’t noticed this on my 49S405 but I don’t have any HE-AAC audio (all my AAC seems to be LC).
I recommend you test against the Roku Media Player to verify it’s the Roku system itself and not a Plex thing - Roku doesn’t care much if Plex playback is a problem but Roku Media Player is theirs to support (I didn’t see it mentioned in your Roku post).
Definitely start a new thread here as well since Plex devs can sometimes put in tickets via partner channels (they did for the AC3 bug) and the Roku devs are pretty active and friendly. 
Mediainfo references might be useful from you and @krisvenden too in that thread? Just to have for checking so others can test or verify same\different audio formatting.
Edit: I see the post you found at Roku forums has the “Roku Media Player” reference in it so all good there! Hope it gets addressed…

Thought I would chime in to report that the audio seems to be in sync now on my Roku TV running 10.0. Seems like it’s finally been fixed.
But like @emichael and @krisvenden I too am having audio dropout issues with HE-AAC.
Looks like forcing direct play off does fix the audio dropout problem for me, so I will continue to leave that off. I was happy that I could turn direct play back on now that my audio sync issue was fixed, but I guess I can’t now until the audio dropout problem is fixed.
What’s discouraging about this, is we went so many months on Roku 9.x on the TCL TV’s before they finally fixed the sync with 10.x but have since broke the audio on HE-AAC files with 10.x. I worry this could be a problem until Roku 11.x update for the TCL tv owners. What Plex could totally do to fix this for us, is give us an option to play all HE-AAC files with direct play disabled. I tried that last night and the audio dropouts are gone. However, I have to change the setting back to play 4k files or any other files and it’s such a big nuisance to have to go back and forth just to get normal play results…
Looks like some workaround help is on the way for the HE-AAC issue: Plex for Roku - #271 by ljunkie
Wow! Huge props to whomever at Plex put that workaround suggestion into the preview channel! Awesome! Thanks so much!

I just tried it out, and it seems to work great! Not hearing any dropouts! Thanks, @ljunkie !
