I am routinely but erratically getting an error when presenting audio files. The error relates to opening files. Superficially, it looks like something is wrong with the file itself. This is contradicted by the fact that the same file will be played at other times in the script without issue. An example error message is below.
Has anyone encountered this before? Any suggestions for troubleshooting?
