It appears that a write protected socket was established as a symbolic link between an audio file and the binary of the audio itself.
We are unable to remove the files and the holding folder. Attempted all possible combination of RM that I could think of and then graduated to shred. We are unable to do so:

I would boot a live Linux cd, perform an fsck on the partition, mount it, and try to delete any instances of this that remain.

After the fsck, make sure the immutable flag is not set on those files. Check with `lsattr`.

I appreciate the information, unfortunately before anything else was tried someone deleted the data instead of fixing it, causing a loss of important data. The issue has not been completely resolved and will perhaps become an ongoing issue... more later.
