So, I've previously been using my own OpenAL code but I recently started using CD instead, because I didn't have anything written to clean up and reload sounds. We're adding levels to a game and will have many sounds for each level with little to no overlap. So, I'm writing code so that all the buffers are cleared and then reloaded when a new level is loaded.

Problem I'm getting is that some buffers refuse to unload. Im stopping all sounds prior to the unload loop, which iterates through the 32 buffers and calls unloadBuffer on each. The log results are as follows:

2010-02-08 15:14:17.444 [5686:207] Denshion error deleting buffer: a003

2010-02-08 15:14:17.457 [5686:207] Denshion buffer 31 successfully unloaded

If I leave out the unload and instead let loadBuffer handle the unloadBuffer call, I get the same errors. For example:

2010-02-08 15:14:17.480 [5686:a517] Denshion: Loading openAL buffer 0 tap.caf
2010-02-08 15:14:17.487 [5686:a517] Denshion: non empty buffer, regenerating
2010-02-08 15:14:17.488 [5686:a517] Denshion: error deleting buffer: a004

Since I stop all sounds prior to unloading, I don't imagine the sound playing to be an issue.

Each time I unload and load buffers, more of them throw errors on load.

Anyone have experience with this or have any suggestions? Much appreciated.
