SYMPTOMS
There have been reports that the Audio Codec 97 (AC97) Driver Development Kit (DDK) sample file causes a Bugcheck 0xE6 error during audio processing (that is, during playback of audio or while the sound card records audio). This can cause the computer to stop responding or to display a stop code error on a blue screen that indicates this Bugcheck error.

This problem occurs when you use the AC97Smpl.sys driver file that the sample builds.



CAUSE
This problem occurs because parameter 1 of the bugcheck is set to 0x0F. This setting indicates that either the driver or the hardware wrote past the end of its allocated Direct Memory Access (DMA) buffer.



RESOLUTION
There is no known resolution for this problem right now.
