Bug ID: 53126
           Summary: mmdevapi:render - test_clock() has timing-related
                    failures
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mmdevapi
          Assignee: [e-mail]
          Reporter: [e-mail]

mmdevapi:render - test_clock() has timing-related failures:

render.c:1114: Test failed: Position 54256 too far after playing 100ms

https://test.winehq.org/data/patterns.html#mmdevapi:render

These happen on Windows and Wine and are quite frequent but the position
changes on every run causing the failure to always look new.

It may be possible to reduce the frequency of the failures by improving the
accuracy of the timing measurements but it's not clear if the failures can be
completely eliminated without making the timing margins meaninglessly large.
