Bug ID: 47868
           Summary: test_notify() dsound:dsound test is unreliable
           Product: Wine
           Version: 4.17
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: directx-dsound
          Assignee: [e-mail]
          Reporter: [e-mail]

The test_notify() dsound:dsound test fails regularly but not systematically:

dsound.c:1085: Test failed: expected 1. got 258

https://test.winehq.org/data/tests/dsound:dsound.html

Most failures happen on *real hardware* Windows 8.1 machines: cw-rx460-32,
cw1-hd6800-t32 and cw2-gtx560-t64. It also happened at least once on
cw2-gtx560-t64 while it was running Windows 10 1709 (tag cw2-gtx560-1709-t64).

Finally it happens just as much in the 32 bit tests and in the 64 bit ones.

This test was introduced in the following commit:
