Media playback on PS4 audio gets out of sync

June 28, 2017

Hi

Yea, so the audio gets out of sync after about 10 minutes of playback, if i stop the media and then play it again it's realigned itself, i know its not the content as it works fine when playing it back on my media server.

The only change has been the update to the most recent version of Emby, it has been happening for a while though i think since the about a 5/6 weeks ago.

Is there any information i can provide to hunt down the source of the problem?

Hmm i haven't had the problem since updating so i'll checked.

I do have another problem with teh latest stable release my video won't play, the code is below, still..i'm not sure why emby wants to transcode it.
