Better Together W10 Beta Sound bug

occasionally when walking on a stone, concrete or stone brick surface the full walking sound does not play and instead cuts off roughly 1/2 to 2/3 way through the sound, this also effects both grass and wooden blocks but to a lesser degree with the exception of a rare occasion where the grass sound only played for roughly 1/4 of the time it should of. This issue only seems to effect my game when i walk around onto multiple blocks and does not effect me if a move only slightly while staying on the same block.
