Audio stutters in video only

Hi,

Hope this isn’t a hornets nest of a problem, but any advice appreciated.

When I play music the audio is perfect. However, whenever I play any video source the audio drops out briefly every few seconds. The video continues to run smoothly, but the audio seems to briefly cut out. Any ideas?

Same issue in Kodi 16.1 & 17 Beta 5 on Windows 10.

Can happily advise of any other settings if I know what would help.

Any help really appreciated.
