[Bug 12286] New: regression: sound: first fragmented, now the ends are chopped off

http://bugs.winehq.org/show_bug.cgi?id=12286

Summary: regression: sound: first fragmented, now the ends are
                    chopped off
           Product: Wine
           Version: 0.9.41.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Since 0.9.40 I am having problems with sound playback. The application is the
Arindal MMORPG-Client (http://www.arindal.com/), but it uses standard QuickTime
to play sound (installed QuickTime 7.2.0.240).

The first regression was introduced in 0.9.40. Before that, sound was playing
fine. With 0.9.40, sound would no longer be played continuously, but all the
sounds (in my case the sound effects of the game) were played fragmented and
choppy.

A git bisect shows that this is the problematic commit:

breakage.

Based on a patch by Peter Dons Tychsen.

The second regression (or partial fix of the first regression?) was introduced
in 0.9.41. Since then, sounds will play continuously again, but very often (not
always) the ends of the sound are chopped off (the last 0.2 seconds or
something like that), so that very short sounds are no longer played at all,
especially if many or multiple sounds are played in short succession. In
addition, sometimes fragments of the "missing" sound bits are played at a later
point, for example, when another sound starts playing.

Unfortunately, I cannot test whether this has been fixed after 0.9.50, since
Arindal will no longer run in current wine versions due to bug #11989.
