Programmer's Guide references use of alSourcei, not alGetSourcei

[mhamilt]

Documentation for use of alSourceQueueBuffers and alSourceUnqueueBuffers such as Queuing Buffers on a Source Page 14 and Multi-Channel Buffers Page 140 as well as the reference for both methods one page 59/60 states the use of alSourcei and not alGetSourcei to get info about processed buffers.

Not a huge deal, but maybe enough to throw someone off.

There should also likely be a separate issue that some kind of auto-generated HTML documentation would be preferable to the current PDF.
