audio not working on one post

Hello all,
How do I fix this without uploading the file to the media library again?
My host limits files to 10 mb, so I had a couple of airchecks deleted. Two of the three I was able to update without issue, but the one linked below won’t update. Is there any way to fix this without deleting the file and uploading again? https://bobsairchecks.x10host.com/2015/07/31/wpst-july-15-2015/
