I suspect it's the way they've been built/installed, and the addon libraries haven't been added to the LD_LIBRARY_PATH as they would if they were downloaded and installed. It's not something I'm going to be able to fix any time soon, I'm afraid - probably one of the reasons why these addons shouldn't be shipped as part of the image...

Edit: Although saying that, all the shared libraries from the other addons (visualizations, pvrs, kodi libraries etc.) are being loaded, so maybe it's a problem with whatever addon is trying to load this audiodecoder - is it up to date with the latest binary addons/platform changes? Hmmm...
