Well, just four in the ARI resource code that I saw. I'll have them taken care of in the next update.

Apparently people don't like that. This patch changes that behavior so that the sound will be queued at the end of any existing controls if they are running.

Tested playing of multiple files in a row. Tested playing of multiple files in a row and then after a sequence finished, playing additional files so that new channels would have to be created. Tested playing sounds right as other sounds were concluding. I wasn't able to break it (although I wouldn't be surprised if there is a possible condition where you can grab a control as it is finishing up its queue and then attempting to add a sound to a finished queue causing the playback to fail. I don't think this would break things in a profound way, it just might possibly make one sound fail to queue under extremely unlikely conditions).
