Issue with different plarforms

Hi.
I have this page here:
https://exodusinteractiveforum.com/haiku-test/

With multiple haiku mp3’s

Here is what a test revealed and I really need a solution.

1. I clicked play in both IE and Chrome, and hit pause sometimes. I ran each podcast about 10 minutes.

2. I did the same on the iPad and Android phone; HOWEVER, we had the same problem with the files on iPad and the iphone. For example, on iPad, podcasts 4, 5 and 6 did not play. When the page loaded, they showed the file as 00:00 / 00:00. I hit refresh a number of times and was not able to get anything. Podcasts 1, 2, 3, and 7 played fine.

3. Same issue with the Android phone. Podcast 7 would not play. All the others played fine. Do you have any idea what is causing this? They all work on desktop browsers, but certain files don’t seem to load on the mobile devices (and there is a variance even among the mobile devices).
