I am having the same problem with the Quantum Access and VLC media player. I even tried to copy the .mkv or .mp4 file directly to the on-board storage of the Quantum Access…same result. The audio stutters. Adjusting the delay with the “J” or “K” keys doesn’t fix the issue. One more note…I tried the Windows Media player and it works fine on the same file.
Anyone have a fix?
