So I've added about 9 new audio files to the add-on, following the instructions, converted and tested them externally in .ogg format, and added them to the config file. They display in game in the gui in both smp and ssp, and the klaxons can play the default sound files fine. When I select and try using one of the custom files, Minecraft loses all audio until I fully restart it. Most of the files are smaller than the default ones. Is this a known issue, and if so, where did I mess up?
