Details

In the forums it was reported that gapless playback does not work reliably in svn. Working files could be produced with lame 3.96, older files created with lame 3.90 do not work (see: http://forums.rockbox.org/index.php/topic,27736.0.html).

The gapless information is read during parsing the Xing header. The code had an error in this section as it did not mask the upper 4 bits during a read operation (see the patch below). Therefor gapless did only work with files which had those upper 4 bits set to 0 (= enc_delay was divisible by 16).
