             Bug #: 30234
           Summary: CSoundManager::Create fails on file names with >= 156
                    characters
           Product: Wine
           Version: 1.4
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-dsound
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: sarastro.admin+wine at googlemail.com
    Classification: Unclassified


Steps to reproduce:

 - Download an application that loads sound files. I used the „PlaySound“
example from the DirectX Samples, available from the SDK at
http://www.microsoft.com/download/en/details.aspx?id=21416 (together with the
source).

 - Create a set of test files with increasing file name length. I used the
following command (where Sifa.wav is a dummy wave file):

for i in `seq 10 156`; do let j=$i-3-${#i}; name=`seq -s "_" $j | sed
's/[0-9]//g'`; cp Sifa.wav $i$name.wav; done

 - Create a list of the files and their full name length (it is important to
use the full Wine path here):

find /home/jojo/.wine/dosdevices/z\:/Zusi3/SoundTest/  | awk '{ print length,
$0 }' | sort -n

 - Launch the test program and try to open any of the test files.

Observation:
 - Any test file whose complete name is less than 155 characters long can be
loaded and played without problem
 - On any test file with a name greater than or equal to 156 characters an
error message "Could not create sound buffer." is displayed.

The relevant code from the sample is

if( FAILED( hr = g_pSoundManager->Create( &g_pSound, strFileName, 0, GUID_NULL
) ) ) { … (display error) }

where "strFileName" is defined as "static TCHAR strPath[MAX_PATH]" and
"g_pSoundManager" is defined as "CSoundManager*".
