Audio Driver Migration (Windows Embedded CE 6.0)
1/6/2010
Effective with Windows CE .NET 4.0, a different default size is used for waveform audio buffers than in Windows CE 3.0 and earlier. The new default size is 2 KB. Users may hear distortions if the size of the wave buffers that an application produces does not match the size of the buffers that the driver expects. For more information about how to adjust the driver settings, see Audio Driver Registry Settings.
Effective with Windows CE 5.0, support for DirectSound has been removed. Instead, use the waveform audio API.
