01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1331 * Playback immediately stops after the non-pow2 buffer

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1334 * 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	1340 * This fix addresses this issue, however it may break in
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1341 * other conditions. Always decode in buffer sizes of powers of 2.

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1343 * The HACK:
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1344 * 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	1345 * to meet the user requested buffer_size which
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1346 * is probably a nice number OpenAL likes, in
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1347 * hopes to avoid a possible Loki bug with
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1348 * short buffers. If looping (which is the main
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1349 * reason for this), the negative side effect is
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1350 * that it may take longer for the loop to start
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1351 * because it must play dead silence. Or if the decoder
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1352 * doesn't guarantee to return the requested bytes
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1353 * (like Ogg), then you will get breakup in between
