Facebook and YouTube Audio Issues for Multiple Users

Over the last month we have encountered audio issues on our church stream. Some users are getting clear sound while others are having issues ranging between low sound, no sound and choppy sound. This is all being reported at the same during the streaming session. This has been happening each time we go live and it's on both platforms. Does anyone have any idea on where we can look to troubleshoot this issue. Each time we go live we do an audio check internally at the church on multiple devices (mobile phones, laptops, iPads and desktops) they all have good sound. Any suggestions would be appreciated!
