           Summary: Very fast audio in Jelly no Puzzle on OS X
           Product: Wine
           Version: 1.7.33
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs@winehq.org

Starting in Wine 1.7.33, the music in the game "Jelly no Puzzle" plays
extremely quickly--more than 4x normal speed.
This applies specifically to the *music* in Jelly no Puzzle, not the sound
effects, which appear to be unchanged.  Nor does it apply to the audio of any
of several other programs I've tested.
This problem is observed on two computers running Mac OS X 10.6.8.  The problem
does not occur in Wine 1.7.32 or any earlier version I've tested; it is a
regression beginning in 1.7.33.  The versions of Wine are installed from
Macports.  I've not tested any other platforms.  The problem reproduces with an
empty wineprefix.
Jelly appears to rely on a freeware program called "PxTone"
(http://en.wikipedia.org/wiki/PxTone ) to synthesize its music (Jelly comes
with a "pxtoneWin32.dll" file).  I imagine a change in Wine 1.7.33 has broken
some assumption made by PxTone.  It sounds like the musical notes are played on
top of each other; they have the right pitch and duration, but each note is
played as soon as the CPU can afford to play it, rather than after the previous
note finishes (or whatever the appropriate delay may be).  I'd therefore
suspect that either some timing-related function is to blame, or some function
returns immediately that used to block.
For reproducing and testing, Jelly no Puzzle is freeware from:

Ticket #37630 seems similar, but it references a problem beginning in 1.7.31,
so it may not be directly related.
