I’m not sure if I’m hitting the same bug, but it seems possible: my audio doesn’t seem out of sync to me but is completely garbled. It sounds like radio cracks and hisses; you can kind of hear the talking but it is completely unlistenable. Filetype doesn’t seem to matter and disabling Direct Play (or Direct Stream) doesn’t seem to matter. This is definitely a newer bug, though, as I have changed nothing about my setup in the last year but this is a new issue. Hoping a Roku fix will work for me too; I’m on an Express Stick.
That could be related to transcoding to MP3 and your client hardware not handling it well? It could be a hardware issue - stuff does break - that’s coincidental to these other bugs.
I would definitely start a new thread with the usual details for troubleshooting (server, client, hardware, audio settings and setup, etc) to have some folks help you track it down.
Throwing my hat into the ring on this. Not sure if it’s the exact same issue but recently (past week or 2) I’ve noticed severe audio issues on my 2 TCL Roku TVs. Sometimes the audio is wayyy out of sync. Other times it completely cuts out for about 5-10 seconds. A couple weeks ago I wrote a .net console app that converts my media files to h264 and AAC because I got sick of having stuff not work (my NAS isn’t beefy enough to transcode). So figured by just converting everything to a format that the Roku client supports natively, direct Play would always work and no more issues with server not being powerful enough to xcode.
But that’s when I noticed the audio issues. It’s not the files as I’m able to play them on our ipads with no audio issues. It definitely seems related to the issues in this post. I can confirm that disabling Direct Play does fix the audio cutting out. Guess my NAS is able to transcode audio just fine, at least on this file I’m testing on. Very strange, as we’ve not had a single issue like this on our TCL Rokus for years of use with Plex. Will keep monitoring this thread and any Roku software updates.
Thanks for all the replies, all.
I’ve discovered that encoding the audio streams in MP3 fixes the Roku direct stream sound issues. Must be an issue related to AAC codec. I’ve converted quite a few eps from aac to mp3, turned Direct Stream back to Force, and I no longer have problems. Hope this helps someone else.
If you look through the topic posts you’ll see there were two different issues - I summarize them here.
Essentially - you have an AC3 in MKV bug which is a Roku issue introduced in 9.4 and there was a transcoding 5.1/7.1 to MP3 bug which Plex has fixed in recent Roku app update.
By turning off Direct Play on your Plex app on Roku you can get around the AC3 bug until Roku fixes it and updating your app you will fix the 5.1/7.1->MP3 transcoding bug. This should avoid having to do any conversions.
Everything is out of sync! Very sad.
If you follow the posts here you shouldn’t have any audio out of sync; Plex updated recently to fix the MP3 transcoding bug and turning off Direct Play works around Roku’s issue with AC3\EAC3 (please contact Roku if you’re experiencing that one). Nobody is “very sad” right now - just annoyed waiting for Roku to fix their bug. What is still “out of sync” for you?
Everything higher than stereo is OOS. i don’t have many avi anymore so an MP3 fix doesn’t help me much. It all plays fine thru the web player.
The fact you said
indicates what I said wasn’t understood so you may be missing the context of this thread and the bugs being specifically discussed and resolved.
This summary from an earlier post breaks out the two specific bugs discussed in this thread.
So which bug are you experiencing? AC3\EAC3 in MKV audio delay (#1 in the summary and primary bug in this thread), or 5.1/7/1->MP3 transcoding audio drift (#2 in the summary)?
If #2, that is fixed in the latest Roku Plex app update.
If #1, flip your Plex Roku app’s Direct Play setting to off but leave Direct Stream enabled - like I mentioned - and you won’t have delays anymore. And please report it to Roku to help get it fixed.
If neither of those line up with your “very sad” situation the you’ll want to start a new thread with the usual specifics and then someone can help you out with your new issue.
Do you need to be so condescending? I have done the direct play flip for a couple months now with very mixed results, OOS issues remain either way.
You haven’t provided any specifics yet and the statements you have made are vague or indicate a misunderstanding of the issues and resolutions presented in this thread. I was trying to be helpful by summarizing this long thread and asking for your cooperation to get relevant information to help with resolution since nobody but you know that information, but if you don’t want help in resolving your issues and you just want to voice frustrations that’s your choice.

If you are the only person who is going to reply about this obvious plex player problem on roku tvs, then i want my plex pass money back. seriously is this what you people call support after the money i paid?
I’m not an employee. You’ll see an employee reference by the username if it’s a Plex representative commenting in these forums (mine says “Plex Pass” just like yours).
I recommend you create a new thread for your issue/complaint. That might be your most effective option.

Hi. Just thought I’d share here as I managed to fix this particular issue by enabling "Auto-adjust display refresh rate” in the advanced system setting of my Roku streaming stick+. DTS was working fine but anything ac3, DD, DD+ was horribly out of sync. With the setting enabled, no more sync our audio dropouts. The only thing is the screen flashes off and off when you start to play a movie, presumably when the refresh rate is changed. The setting was also not present on my cheaper Roku Express, not sure which other models have it. Hope this might help some people.

Nice! Good to know! It might be worth reporting to Roku to help get a permanent fix out maybe; it seems the default is “off” and before the 9.4 update having it off didn’t cause these audio issues.
Roku’s Info about the setting.
Looks like, based on that article, it is only available on Roku’s that support 4k.
I can’t see a reason NOT to enable this setting - besides possible “black screen flashes” - but does anybody have experiences around this setting? Is having this enabled better/worse than disabling direct play or is it just a preference? Don’t TVs auto adjust for this - though it looks like Roku sends 60pfs as default… gah! I liked the Roku so I didn’t have to fiddle… 
Edit: Looks like, from this article, that this setting can fix audio sync issues but may introduce some image jerkiness - but another article says NOT enabling it introduces jerkiness. Reading a few other articles seems to indicate the “auto HDMI” should really take care of most of the playback issues related to frame rates … hopefully we’ll get a more reliable permanent fix from Roku, eventually.
Edit: Setting wasn’t available in my TCL Roku TV
Posted in the other thread that my dedicated Roku devices aren’t having the audio delay on my test file anymore but my TCL TV still has the issue (auto refresh rate disabled). Anybody notice any similar experiences lately?
I don’t show any Roku OS updates on any of the devices but I don’t know if smaller big fixes might get updated without notice\change and I know the dedicated devices get updates much later than the TVs get them usually.
For me, this issue only ever occurred on our Roku TV and never any of our separate Roku devices.
Plex can you apply some corporate pressure on Roku please? Everyone let’s jump on Roku’s social media and make some noise

Plex filed an issue with them - and Roku isn’t responding to my ticket anymore - but I definitely agree that more pressure could help.
It does seem like maybe a fix is out for dedicated boxes but not for the TVs yet - we didn’t get much reporting back on it though so it’s just anecdotal. The TVs definitely don’t get updated as quickly.
It’s just so annoying though ain’t it?
Still seeing issues on TCL Roku TV despite a minor update … dedicated devices are working fine (for me, outside of a singular case).
Maybe the Roku OS 10 rolling out shortly will finally fix it.
