KODI:

• Have you tried switching between WASAPI and DIRECTSOUND in system audio?
  

• Is keep audio alive off / send low volume noise disabled?
  

MADVR player settings in KODI:

• Did you remember to update the LAV filters in:
  

KODI INSTALL FOLDER\system\players\dsplayer\LAVFiltersCopy these directly from you windows program files LAV filter install, these should always be up to date ideally.

• Have you tried system rendered instead of sansear, or even reclock just to see if it goes away?
  

• Audio filters / have you turned off / on bitsteaming?
  

• Make sure use DTS-HD for all DTS types is disabled
  

Can you record it so we can hear it? 

Switching the system audio from WASAPI to DirectSound did nothing.

I have tried turning off the keep audio alive and send low audio signal, but they had no effect.

I updated LAV, but it did nothing.

I switched DSPlayer from Sanear to the system default, tried both WASAPI and DirectSound, but the sound still occurred. I have not tried ReClock yet.

Turning off bitstreaming also had no effect.

DTS-HD for all DTS types was already off.

Here's a link to an audio clip that I recorded: https://www.dropbox.com/s/5zmpw75enarvgp...1.m4a?dl=0

Interestingly, the sound only occurs in the surround left and surround right speakers of my 11.1 setup.
