Video ahead of audio

Very often when playing some concert video files, the audio is behind the video. There are many ways to correct the other way around but this seems a lot more complicated. I have my LG C1 connected to my SA30 through the headphone output on the rear of the LG C1. This is the only option for me right now because of the location of the TV and the SA30. Any ideas if it is possible to correct this? My old Popcorn Hour A500 is the only one that can correct both ways.
