Assume that you have a computer that is running Windows 7, Windows Server 2008 R2, Windows 8, or Windows Server 2012. The computer is installed with a video card that is compliant with Intel High Definition Audio Specification for HDMI. When you try to shut down the computer, you may receive a Stop error message that resembles the following:
STOP: 0x00000019 (parameter1, parameter2, parameter3, parameter4)Notes
- This Stop error describes a BAD_POOL_HEADER issue.
- The parameters in this Stop error message vary, depending on the configuration of the computer.
- Not all "Stop 0x00000019" errors are caused by this issue.
- This issue occurs when system tries to stop the process of the High Definition Audio Controller driver on the video card. The error occurs in the Hdaudio.sys driver.
The issue occurs because the Hdaudio.sys driver tries to process the audio information when the uninitialized internal firmware memory within the video card is set in a certain manner. The result is internal pool corruption. You receive the stop error when the Hdaudio.sys driver is unloaded, a process that typically occurs when you try to shut down the computer.
