01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1330 * Playback immediately stops after the non-pow2 buffer

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1333 * 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	1334 * and hope that SDL_sound always fill it. (By lucky coincidence,

a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5705 * I can't find it in the spec, but for at least some of the
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5706 * implementations, if I call play on a stopped source that
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5707 * has processed buffers, all those buffers get marked as unprocessed
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5708 * 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	5709 * processed, on resume, the earlier 24 buffers will get replayed,
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5710 * causing a "hiccup" like sound in the playback.
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5711 * To avoid this, I must unqueue all processed buffers before
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5712 * calling play. But to complicate things, I need to worry about resyncing
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5713 * the circular queue with this since I designed this thing
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5714 * with some correlation between the two. However, I might
a8a8fe374984 Subversion era Eric Wing <ewing . public \|-at-\| gmail . com> parents: 0 diff changeset	5715 * have already handled this, so I will try writing this code without
