<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">If command_count here is 0 and a new command is added before ao2_lock is added, control_command_count will be greater than 0 and the loop will make another pass (which will mean the new command will get dispatched). This addresses one of the concerns mmichelson raised.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Previously, if you played an audio file and then played another before the first finished, the second audio file would start playing immediately as it was called overlapping the previous sound. 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.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Tested for playback channel wrapper leaks, tested to make sure control objects were being destroyed when they fell out of use. Tested playing of a single file. 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).</pre>
