Fri, 30 Sep 2011 17:48:23 -0700	Eric Wing	Fixed bug with seeking channels with predecoded samples. The OpenAL 1.1 spec specifies that a playing source should automatically jump when already playing. The code was unnecessarily recalling alPlaySource again which is not necessarily the correct thing to do. I think the previous code is another remnant of the Open 1.0 era. Also fixed bugs in the return codes for seek and rewind. For single channels, the return code was 0 channels processed in ALmixer which resulted in returning false to Lua. The implementation now should return 1/true for single channels, but 0/false for no channels. Errors will return -1/false.
Fri, 30 Sep 2011 16:44:08 -0700	Eric Wing	Workaround: There is a terrible OpenAL regression bug in iOS 5 dealing with streaming sources. alSourcei(source_id, AL_BUFFER, AL_NONE); fails to clear queued buffer queues on a streaming source. The workaround involves manually dequeuing the individual buffers before calling alSourcei(source_id, AL_BUFFER, AL_NONE);. But there is an additional race condition bug where the unqueue fails to take, so the included workaround keeps looping until the buffers finally report as cleared.
Thu, 29 Sep 2011 11:33:34 -0700	Eric Wing	Added addition query to get the current number of buffers processed in the new inner buffer decoupling loop because I've been seeing a lot of 59TestingError warnings. I think it is possible the value may become stale after the first iteration of the loop resulting in assumption failures which result in triggering this error.
