Audio out of sync

Setting the Audio Passthrough to disabled for the Plex App itself on my NVidia Shield TV Pro seems to have worked for me.

I just read the posts since my last - this issue MUST be coming from more than one source - in other words, it could be many things, and it could be how they interact in your particular system.

UPDATE: Hereā€™s another possible culprit - Letā€™s say that someone has gotten some of their media from some questionable sourcesā€¦(be careful what you say!). Some of that questionable media may have been altered by the source to allow for a variety of functionality. One common alteration is language, and if the unit doing the altering doesnā€™t speak English, checking lip sync isnā€™t that important. So, when trying to track down this problem, be consistent with your media, and consider the source of the media that gives you problems. Is there particular media thatā€™s always out of sync? Where did it come from? Is there something strange about that mediaā€¦like maybe the file size seems way too small? Or it reports 720p/1080p, but you look at the screen and proclaim, ā€œBaloney!!ā€?

This is still happening on my end as well for the out of syncā€¦ i have to let it play a bit then go back a few to sync again when it gets way out of wack

105

Having the out of sync issue as well, go back 15 seconds and itā€™s fine but eventually goes out of sync again. HDHomeRun and Nvidia Shield - seems like a MPEG2-TS codec issue? My source is recorded live tv DVB-T using HDHomeRun. Using the HDHomeRun app doesnā€™t display these issues.

This happens with media Iā€™ve ripped myself (x264 or x265) AAC audioā€¦(all direct play). If I start an episode from the beginning, itā€™s fine. But if itā€™s been partially played and I start, sometimes (not always) it will be out of sync. Pausing/starting fixes it. But itā€™s so random!! Again, itā€™s direct play (no transcoding at all)

Was having the same sound delay over 4k fire stick. I changed the video from Original Quality to automatically adjust. For the moment it seems to be helping.

I am having this issue in win10, web player(direct play). Tried enabling transcoding and it kinda worked, most of the delay is gone, but is highly unpratical since my server is a rpi3.

All these months laterā€¦when/if I find something out of sync (which isnā€™t very often) but itā€™s always AC3 5.1ā€¦ My other problem with sync was most .AVI files that had MP3 as audio (but Iā€™ve re-encoded most of those so that they direct play). Anyway, when this happens, all I have to do is pause the video and start it back and itā€™s in sync again and stays in sync.

Hello everyone.
I have same issue with Plex App running on Samsung TV.
I have issue only with some files, weird thing is that it is mainly on some in 720p where 4k files work perfectly fine.
When I turn of Direct Play and Direct Stream it works perfectly fine but then I have to which that back on each time I want to play 4k file because my Plex Server canā€™t cope with trnascoding 4k filesā€¦
Very irritating.
Any fix ideas anyone?

So, I have an Android TV Box and have recently started using the Plex Media Server. I have had sync issues with the sound but Iā€™ve found a quick fix. Basically, press the select button to highlight the Pause/Skip Forward options etc. Then press up to highlight the time bar. Press right to skip forward by 30 seconds, then press back (possibly three times as it rewinds 10 secs at a times) to get to where you were and the lip sync will hopefuly be fine. It works for me anyway! Hope it helps.

I have been using my setup with out issue for a while so consider it stable. I have recently invested in a couple of NVida Shield (new one model).

For content I have ripped directly to MKV no issues. My issue seems to come from recording via HDHomeRun/Plex recording. I get c10 seconds of audio drift which seems to be when there is an ad break or programme credits. As with other comments if i hit the rewind it goes back in sync unitl the next break.

Same for both a TV with both TV/AMP setup and one that just has the internal speakers.

Iā€™ve had this issue occasionally on my Shield Pro with Live TV from an HDHomeRun, Noticed today that itā€™s happening way more often, almost immediately on any channel. Iā€™ve tried some of the suggested fixes mentioned through this thread and have had no luck.

Iā€™m tempted to try Channels, but donā€™t really want to pay for that when I already have Live TV capability through a lifetime Plex Passā€¦

Iā€™m having the same issue , but with an AppleTV running the Plex app , video and audio being passed through an Onkyo TX-SR608 via HDMI. The setup is basically AppleTV >Onkyo Receiver>Vizio TV. My Server is being run off a local MacMini.

Iā€™ve searched for these threads to try and find a setting that worked to bring my audio in sync. First, it was to check for any lip sync or delay features, but all those did was push it out of sync further.

So I came back to the Plex settings. I ended up telling the Apple TV to no longer direct play and transcode everything. This is annoying, since you have to do it on every show or movie I watch.

Next step that I found was to turn on ā€œUse Old Video Playerā€ setting. The audio would drift again when watching a video, you could set it to ā€œconvert automaticallyā€ from the pull down and it would come back in sync ā€¦but then drift again.

So, at this point I have run out of suggestions. Hereā€™s what I do know: Netflix doesnā€™t have this problem on my Apple TV. Amazon Prime doesnā€™t have this problem on my Apple TV. No other streaming app does this.

This is seriously frustrating and game breaking for me.

I wish there was a solid fix for my setup.

We have same problem
But all we do go back a few frames on the film and we find all is good

Yes this works for me too, skip back 5 or 10 seconds and then when it continues to play its in sync.

117

I also have the same issue with two shows. Both are a few years old and MKV.

I wrote more about it here:

Skipping forward or back will reset the audio sync issue. It happens on two of my TVs, slightly different setups:

Nvidia shield (2017) + Samsung TV + Sonos Beam

And

Nvidia shield (2015) + old LG TV w/ tv speakers

A few people said itā€™s your tv, itā€™s unlikely it is.

Thank you. Changing the sound mode on my soundbar fixed it. It is now in sports mode

I found re-encoding the media using handbrake will work.

I used to use Plex on an Apple TV, no problems at all.

Recently got a TV with Android TV built in, and now some content has a slight but noticeable audio sync issue, with the video a fraction of a second ahead of the sound. Itā€™s quite distracting and annoying. Seems to happen mainly with 720p content with 5.1 audio.

I use a Sonos soundbar, there are no options for adjusting the sound if itā€™s behind the video, you can only delay it if itā€™s ahead. I disconnected the soundbar to rule that out, and the problem is the same.

If I play stuff through the the Plex addon in Kodi, it works perfectly. It didnā€™t happen via the Apple TV app. This seems totally related to the Android TV app.

I donā€™t want to apply a global adjustment because this only happens with some content. Any ideas, beyond just giving up on the Android TV app and using Kodi?

Iā€™m experiencing this too, but only on shows recorded from live TV that use have surround sound. It starts fine, but gets progressively worse over time. Pausing then unpausing doesnā€™t fix it. Going back 10-20 seconds fixes it for a while, but then it starts happening again.

Iā€™m using an Nvidia Shield (as both the server and client), a HDHomeRun, an LG C9 TV, and a Vizio SB3651-E6 sound bar.

Any ideas what I can do to fix it? This thread is long so Iā€™m not sure if thereā€™s good workarounds hiding in the thread.
