01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1142 * The behavior is inconsistent, but one of several things
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1143 * usually happens:
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1144 * Playback is normal
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1145 * Playback immediately stops after the non-pow2 buffer
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1146 * Playback gets distorted on the non-pow2 buffer
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1147 * The entire program segfaults.
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1148 * 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	1149 * and hope that SDL_sound always fill it. (By lucky coincidence,

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1151 * 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	1159 * to meet the user requested buffer_size which

a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5273 * implementations, if I call play on a stopped source that
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5274 * has processed buffers, all those buffers get marked as unprocessed
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5275 * on alSourcePlay. So if I had a queue of 25 with 24 of the buffers
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5276 * processed, on resume, the earlier 24 buffers will get replayed,
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5277 * causing a "hiccup" like sound in the playback.
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5278 * To avoid this, I must unqueue all processed buffers before

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	5571 * The Loki test code does it 3 different ways. They
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	5572 * set the last value to 0, or they set it to ALC_INVALID,
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	5573 * or they set two final values: ALC_INVALID, 0
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	5574 * In Loki, 0 and ALC_INVALID happen to be the same,

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	5579 * to be a coinicidence because it's defined to 0.
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	5580 * Creative provides no source code, so I can't look at how
