Symptoms

Assume that you play an audio file in Windows Media Player on a computer that is running Windows 7 or Windows Server 2008 R2. However, when you try to use another application to play another audio file at the same time, the application does not play the second file. Additionally, you receive an error message that resembles the following from the second application: 
0x887C0033 AEERR_TIMED_OUT
Note The application tries to play the audio file in shared mode.

Cause

This issue occurs because of a timing problem that occurs in the audio engine. This behavior occurs when the kernel system timer is set to 10 milliseconds by the Multimedia Class Scheduler service (MMCSS). Therefore, a second audio stream occasionally encounters this time-out error.

Resolution

  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
    Collapse this tableExpand this table
    VersionProductMilestoneService branch
    6.1.760 0.16xxxWindows 7 and Windows Server 2008 R2RTMGDR
    6.1.760 0.21xxxWindows 7 and Windows Server 2008 R2RTMLDR
    6.1.760 1.17xxxWindows 7 and Windows Server 2008 R2SP1GDR
    6.1.760 1.22xxxWindows 7 and Windows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows 7 and for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
