Video and audio out of sync when playing 1080p 60fps on Raspberry Pi 2

Question

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.

Answer 1

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.
