I have a 1080p @ 60fps mp4 video saved in a external USB HDD. I've tried playing it on Raspbian in my Pi 2 (the new one, 1 GB RAM, 1 GHz) with Omxplayer, but the audio and video are out of sync. The audio plays at least a second ahead of the video, so it's pretty noticeable. Videos at 30 fps seem to play fine and are correctly synced. I've tried memory splitting with up to 256 MB for GPU, but the problem persists. I've seen other questions regarding this issue but no one seemed to end up being resolved.

1Does it improve if you put the file on the SD Card?– Steve RobillardFeb 19, 2015 at 20:52

I will try tomorrow. The external drive is entirely formated in NTFS.Could that have something to do?– user2859982Feb 19, 2015 at 21:25

It could be the result of latency on the USB bus.– Steve RobillardFeb 19, 2015 at 21:32

Also, how are you outputting the audio?– Steve RobillardFeb 19, 2015 at 22:22

1It seems it's also happening with the file being on the SD card.– user2859982Feb 20, 2015 at 19:56

Solved.These are my current settings related to this:
arm_freq=800
gpu_mem=128
h264_freq=350
force_turbo=1
core_freq=500
Haven't used it for video in a while, but last time I checked it played smooth and without any problem.

2Please post your settings here and on the pi forum as there is no indication there that it was fixed - just to conversation. Thanks! Nov 12, 2015 at 2:05
