Last few weeks I have noticed an audio stutter while I am direct playing videos from my server. The stutter/hiccup happens every minute or so and is very quick.
I first checked the server to make sure for some reason my server resources were bottlenecking but everything seemed fine. I have never had an issue with my PC choking on 4k anyway. Both PC and Roku are hardwired.
The files this has happened to are various. The current one I am on is an MKV 4k DDP 5.1.
I have tried removing the Plex channel on the Roku, did nothing. I did try transcoding the video and it seemed to play fine without issue. When I went back to direct play the stutter/hiccup was back. When I have more time I want to do this again for longer lengths and make sure this is true.
I have done some searches and have seen a mention here and there. Any ideas of what could be causing this? Any possible fixes?
Iām getting the same, just noticed it yesterday. I have 3 Roku Ultras, 2 4660X and 1 4670X and they are all doing it when direct play is enabled. Turning it off seems to resolve the issue. All of them are on 10.0.0 build 4195-46.
Funny thing is, I also have a TCL Roku TV. It was on 9.4.0 build 4120-48 and did not have the problem. I checked for updates and it updated to 10.0.0 build 4195-48 and still doesnāt have a problem.
Iāve seen this issue as well. Currently running Plex 1.23.0.4497 on two different Roku Ultras (4660x 10.0.0:4195). Audio will drop out every few seconds or so. Files I have noticed so far it happening on have HE-AAC Stereo and AAC Stereo format, it might be happening with other formats as well.
Also direct play enabled.
I too am having this issue. It only persists on the Roku devices I have and not on any other devices. I read there was an update on Roku recently and perhaps that is part of the issue? It is just so random on the content that the audio stutters. I hope this gets fixed soon.
Can confirm this is happening to me too on Roku Streaming Stick with server 1.23.1.4602 for the past two months. My current workaround is to choose the highest quality non-direct play version, but itās very annoying to choose every episode.
Not sure if bitrate and sampling rate matters but the movie that stutters every 30 seconds for me has AC3 stereo audio with 160 bitrate and 48000hz sampling rate.
Iāve got AC3 audio tracks in any flavor you want - except sampled at less than 48k. That I know of, at least. If there were anything unsavory happening - Iād be making noise about it, but I canāt find anything to make noise about at my house.
Disclaimer:
I am using The Preview App - 'cause whatever fixes can be made immediately - I want those - perhaps thereās a fix in there everyone needs:
The Roku Preview App is simply a private channel that can be updated immediately with repairs - without having to wait for Roku INC to approve the fixes coming for the Official Channel.
There is no reason NOT to run it - it can be run side-by-side with the Official App - if for some reason you feel you must have it.
Me? I removed the Official App and run ONLY The Preview.
If for some reason I need the official app - itās in the Roku Channel Store (unlike The Preview App).
Roku Plex client: 6.7.28.7055
Plex server: 1.23.4.4712
Iāve tested several files I was having problems with and so far Iāve not had any more issues with the HE-AAC\AAC files with the new client, some EAC3 .MKV files were still giving issues on the Roku. Iāve not had any issues with AC3 of DTS .MKV files. The EAC3 files play back fine in VLC and through the Plex web player. After playing them back several times I noticed that the stutter would happen in the same place. I figured Iād do some testing by āre-encodingā those files and after several tests with Handbreak and finally using xmedia-recode. All that I need to do was to import the files into xmedia-recode and set the video, audio and subs to just copy (no re-encoding) to a new MKV container and āvoila no more issue with that series of files (so far). The only difference between the old vs new files was the new files was about half a meg or so bigger.
So it seems the way the EAC3 files were encoded, were OK, just something weird with the old MKV container that the Roku players donāt like.? Possibly timing sync between the audio and video?
Iāll have to do some more watching but so far my issues seem to be fixed at the moment.
