             Bug #: 31924
           Summary: mixerGetDevCaps does not support mixer device handles
           Product: Wine
           Version: unspecified
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winmm&mci
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: nicode at gmx.net
    Classification: Unclassified


The Windows SDK documentation states: "This function also accepts a mixer
device handle returned by the mixerOpen function as the uMxId parameter. The
application should cast the HMIXER handle to a UINT."

This feature is missing in the mixerGetDevCaps(W) implementation.

It might be fixed by using mixerGetID((HMIXEROBJ)uDeviceID, &uMixerId,
MIXER_OBJECTF_HMIXER) to resolve the handle to an identifier if uDeviceID is
greater than or equal to mixerGetNumDevs().
