I would suspect you are hearing things. Try playing the same file with a desktop media player such as MPC-BE and use the internal audio renderer. Does this noise still persist? If so, it could be some fault of LAV Filters. But I don't think LAV Audio is doing anything suspicious with the audio that Kodi wouldn't also be doing.

As I said, it does not occur with MPC-HC desktop media player, only in DSPlayer itself. I just found out that if the audio is HD (I.e. TrueHD, or DTS-HD, or higher), the noise only occurs for about 10 seconds, with any other type of audio (i.e. AAC, or DD, or DD+, etc.), it occurs all throughout, except pure audio files, such as FLAC. I also confirmed the noise with a friend and they could also hear it. It makes Kodi unwatchable.  

have you tried a seperate portable install with default settings to rule out a corrupt install. 

Where would the link to the portable install be?
