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. The current check is compiled only for iOS and does a runtime version check against CoreFoundation version 674.0. When Apple finally ships a fix, this fix should be amended to not run on fixed versions. Also ironically, it was originally the Apple Mac OpenAL implementation that had a problem with buffer unqueuing which ultimately led to the use of alSourcei(source_id, AL_BUFFER, AL_NONE); This is another reason the workaround is only constrained to iOS. In some cases I've seen, the buffer unqueue also triggers OpenAL errors, however, the current workaround seems to usually avoid those OpenAL errors (even though the buffers fail to unqueue some times). The 20ms sleep seems to avoid the race condition entirely, but when it doesn't, the sleep seems to do something that magically avoids tripping OpenAL errors.

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1335 /* The PROBLEM: It seems that the Loki distribution has problems
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1336 * with Queuing when the buffer size is not a power of two
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1337 * and additional buffers must come after it.
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1338 * The behavior is inconsistent, but one of several things
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1339 * usually happens:
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1340 * Playback is normal
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1341 * Playback immediately stops after the non-pow2 buffer
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1342 * Playback gets distorted on the non-pow2 buffer
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1343 * The entire program segfaults.
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1344 * The workaround is to always specify a power of two buffer size
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1345 * and hope that SDL_sound always fill it. (By lucky coincidence,
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1346 * I already submitted the Ogg fix.) However, this won't catch
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1347 * cases where a loop happens because the read at the end of the
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1348 * file is typically less than the buffer size.
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1349 *
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1350 * This fix addresses this issue, however it may break in
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1351 * other conditions. Always decode in buffer sizes of powers of 2.

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1353 * The HACK:
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1354 * If the buffer is short, try filling it up with 0's
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1355 * to meet the user requested buffer_size which
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1356 * is probably a nice number OpenAL likes, in
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1357 * hopes to avoid a possible Loki bug with
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1358 * short buffers. If looping (which is the main
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1359 * reason for this), the negative side effect is
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1360 * that it may take longer for the loop to start
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1361 * because it must play dead silence. Or if the decoder
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1362 * doesn't guarantee to return the requested bytes
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1363 * (like Ogg), then you will get breakup in between
