PROBLEMS WITH AUDIO SHARING WITH VLC

HI! I HAVE GOT SERIUOS PROBLEM WHILE SHARING AUDIO USING VLC. 

I TEACH DANCE AND I SHARE ONLY THE AUDIO. 

I HAVE USED IT FOR THREE YEARS WITH NO PROBLEMS, BUT IN THE LAST TWO WEEKS MY PARTECIPANTS DON'T HAVE A GOOD QUALITY SOUND AND IT SKIPS FOR SOME SECONDS. 

I DON'T UNDERSTAND WHY AND WHAT'S THE SOLUTION...

I'M TRYING TO USE QUICK MEDIA PLAYER OR IINA... 

HAVE YOU GOT SOME SUGGESTIONS? 

Thanks
