Audio player has disappeared from my blogs

My audio (player) is suddenly not showing up on my blogs and I have added NO additional plugins or made any changes.

https://www.ads-software.com/support/topic/313910?replies=1 – This thread – like so many others on this forum was closed prematurely so I have started yet another to ask what could be causing the disappearing audio when no changes have been made to my configurations?

Thanks for reading
