DTS 5.1 Audio Dropouts

I have an SD card in a flash drive plugged into the USB port in the Z8. I tried playing several mkv files, each with DD 5.1 and DTS 5.1 audio tracks. The DD 5.1 audio tracks play flawlessly while the DTS 5.1 audio tracks have occasional very short dropouts. The dropouts always occur at a certain point in the file and are repeatable. The dropouts occur using the File Manager app or the MX Player app. (I cannot get KODI or VLC media player to play in surround sound, only in PCM 2.0). When I play the mkv files on my Windows 10 PC using VLC media player, there are no audio dropouts in DD 5.1 or DTS 5.1.

Is there are a setting to eliminate audio dropouts? Are there any other solutions?

Success!! I installed and executed the Audio Optimizer. There no longer are any audio dropouts when playing mkv files with DTS 5.1 audio. Thank you SAM.
