Samsung UE50J5550 - MKV audio not sync
Hello,
yesterday I got a Samsung UE50J5550.
With this TV and UMS I got the problem that my audio is lagging behind 2secs or something, its not choppy or anything else. The video looks fine, but it looks like when I start a file: it plays the file for 2secs, then jumps to the beginning and runs with the audio delay.
What I also noticed is that only one engine works, the other 2 tell me to check my network.
I tested my network connected via cable and wireless, both don't work without audio delay.
The TV plays most MKV files without transcoding just fine, but I have some MKV files that my TV does not support and I thought I could just use UMS to play them.
I hope someone can help me. If you need more details just ask.
Thanks in advance
Edit: I saw that I was using the wrong ums version with java 7, changed it to ums java 8 but still didnt change anything! (Do I have to upload a new log with the java 8 version ?)

Re: MKV audio not sync
Okay I have tested several other forced Renderers, but still no luck 
I was browsing the forum a bit more and found a thread with the same problem discussed on page 2:
viewtopic.php?f=9&t=3874&start=10
Looks like there is no solution for transcoding on that TV Series in sight.

Re: Samsung UE50J5550 - MKV audio not sync
Don't mix up two different things (also in case the root cause can be same 
).
Your link describes file with AAC audio track which MEncoder and also FFmpeg don't like when e.g. remuxing is used.
It means in most cases noone see problem as using DTS or AC3 audio track is mostly used in my opinion.
Your problem can be similar as your audio track is FLAC what is also uncommon codec for video files so root cause can be same.
Btw. in your log I saw audio is transcoded to AC3 640kbits and video is not touched. All is then remuxed and stramed to your renderer.
Root cause can be FFmpeg/MEncoder "bug", audio transcoding process, not optimal MEncoder/FFmpeg commandline parameters used and many others.
Try to play with settings if anything change for you as changing "audio bitrate, LPCM transcoding, A/V sync alternative method,..." directly in UMS is only solution how to test it without going to command line.
If you will find working magic formula, then it should be implemented to UMS for everyone
