This add-on functionality was exactly what I had in mind for our site. It is easy to use and the block is also styled very nice.

Being new to version 5.7 I had a need for a quick sermon player add-on for a church project. Purchased this on a whim and it was needing a couple adjustments before it met my needs.

There were some issues with live stream player for the audio plugin. Audio Player is flash anyways so it is not extensible to mobile needs. It needs to be updated for HTML5.
Users requesting RSS/podcast capability which is currently not supported.
There are some styling issues that will prevent it from being usable on mobile devices, also noticed some bugs in Edit forms that needed to be fixed in version 1.0.
I see the need for adding multiple files per sermon which is another improvement that could be made.

All-in all it is a start, but I think it still falls short of meeting the needs of most church websites.
