Having this problem as well. Media streams fine to xboxone, iPhone, laptops, and smart TV just fine, but xbox360 consistently has a serious audio out-of-sync issue.
PLEX! Can we get some sort of feedback on this issue? Is this problem being worked? Is xbox360 even being supported anymore?
Same thing here, I am about to ditch my plex pass and go back to emby since that works great on the 360 through Media Center. Its a shame as the Xbox One app works great, but same files are totally out of sync on 360
it was working before the june update so it is fixable please try to fix that plex we are alot with that trouble, personaly i use 3 xbox 360 on 3 tv so i would really aprecite a fix
still no movement or response on this issue ? 
Still not fixed huh.
Seriously. i’m still running 0.9.16.6 because of this. Works like a champ though. But can’t test DVR now without this fix.
I haven’t bought a Plex Pass yet, and i’m starting to think I never will. There are plenty of people out there with re-purposes XBOX 360’s that don’t need/want to upgrade to an XBOX ONE.
I have the same error, Basically it boils down to this:
Files that work in xbox system video player have lip sync issues in plex ( usually mp3 audio codec AVI encapsulation )
Files that do not work in xbox system video player work perfectly in the plex app ( everything else )
Yep same thing here. Please fix this! Used to not be any issues, cant watch anything on xbox 360 now. Have Plex Pass
Any news? I have the same issue. I converted 250GB of movies with handbreak to mp4. Now the lag is (only) at about 1 secound - still annoying.
Yep still broken. Please devs look into this.
+1 PlexPass subscriber.
Same issue here although playing through firefox on my machine that hosts the plex server the video and audio are in sync. On the xbox 360 it is badly out of sync. My only other option is to test using ethernet rather than streaming over wifi.
Plex do we have a fix to this yet?!?
same for me - only started a few months ago, small files stay in sync, longer files (>30min) drop out immediately once started, and stay out by about 10-15 seconds for the duration of my patience with it.
The following command currently works on plex media server on linux - it will remove mp3 from the xbox 360 direct stream profile.
gawk -i inplace ‘{gsub(/codec=“h264” audioCodec=“aac,mp3”/,“codec=“h264” audioCodec=“aac””);gsub(/codec=“h264,mpeg4” audioCodec=“aac,ac3,eac3,mp3,pcm”/,“codec=“h264,mpeg4” audioCodec=“aac,ac3,eac3,pcm””);gsub(/codec=“h264” audioCodec=“aac,ac3,eac3,mp3,mp2,pcm”/,“codec=“h264” audioCodec=“aac,ac3,eac3,mp2,pcm””);gsub(/codec=“mpeg4,msmpeg4v3,mjpeg” audioCodec=“mp3,ac3,eac3,mp2,pcm”/,“codec=“mpeg4,msmpeg4v3,mjpeg” audioCodec=“ac3,eac3,mp2,pcm””);print}’ “/usr/lib/plexmediaserver/Resources/Profiles/Xbox 360 App.xml”; gawk -i inplace ‘{gsub(/codec=“mpeg4” audioCodec=“ac3,mp3”/,"codec=“mpeg4” audioCodec=“ac3"”);print}’ “/usr/lib/plexmediaserver/Resources/Profiles/Xbox 360.xml”
This client is abandonware guys. Let it go.
Same problem sound out of sync with xbox 360 but on my ipad i play the same movie and it’s ok???
Dear colleagues of disappointment,
Nothing new under the sun if I told you that I’m experimenting exactly the same issue.
Here is what I found on reacttant.com which may be helpful:
This is basically as solved as this issue will be since the 360’s product life cycle is done and they are most likely not going to update the codecs on it. SwiftPanda16 recommends using the Sickbeard mp4 (https://github.com/mdhiggins/sickbeard_mp4_automator) converter or Handbrake (https://handbrake.fr/) to convert problematic files into a codec the XBOX can actually read.
I tried this solution, converted some of my problematic videos (Handbrake) and had my audio / sub sync working properly.
It may sounds very 2000 but as the fix is to buy a new XBOX one, I will tinkering a bit waiting for Santa Claus generosity.

Using the xbox 360 built in system video player and connecting to plex works fine for me. You don’t get the pretty interface of the 360 plex app but since the plex app doesn’t work well…
I found that it is older files that cause this on my 360. my work around has been to optimize the videos. seems to have corrected the issue for me.
