I have sound issues with some video files I want to play from an external HDD with my Raspberry Pi 2 and OSMC. Instead of the video sound I hear a very loud chattering, rusteling sound. Kind of like a machine gun sound in an old video game. The Error only occurs with certain video files, the others work fine. As audio output, I use HDMI as the Raspberry is connected to my projector. This is then connected to my speakers.
As I thought it might be a codec problem, I allready bought and activated MPEG-II and VC1 codecs, but this did not help.
Here some information on one of the malfunctioning files:

I have the same problem with files with the following codecs: V_MPEG4/ISO/AVC (Video) & A_AC3 (Audio)
But V_MPEG4/ISO/AVC (Video) & A_DTS (Audio) work fine... I am thankful for any hint.
Kind regards, Mathias
