DSCAPS_CERTIFIED
Specifies if this driver has been tested and certified by Microsoft.

Flag Name: DSCAPS_CERTIFIED


DSCAPS_EMULDRIVER
The device does not have a DirectSound driver installed, so it is being emulated through the waveform-audio functions. Performance degradation should be expected.

Flag Name: DSCAPS_EMULDRIVER


DSCAPS_PRIMARY16BIT
The device supports Primary sound buffers with 16-bit samples.

Flag Name: DSCAPS_PRIMARY16BIT


DSCAPS_PRIMARY8BIT
The device Supports Primary buffers with 8-bit samples.

Flag Name: DSCAPS_PRIMARY8BIT


DSCAPS_PRIMARYMONO
The device Supports Monophonic Primary buffers.

Flag Name: DSCAPS_PRIMARYMONO


DSCAPS_PRIMARYSTEREO
The device Supports Stereo Primary buffers.

Flag Name: DSCAPS_PRIMARYSTEREO


DSCAPS_SECONDARY16BIT
The device Supports Hardware-Mixed Secondary Sound Buffers with 16-bit Samples.

Flag Name: DSCAPS_SECONDARY16BIT


DSCAPS_SECONDARY8BIT
The device Supports Hardware-Mixed Secondary buffers with 8-bit samples.

Flag Name: DSCAPS_SECONDARY8BIT


DSCAPS_SECONDARYMONO
The device Supports Hardware-Mixed Monophonic secondary buffers.

Flag Name: DSCAPS_SECONDARYMONO


DSCAPS_SECONDARYSTEREO
The device Supports Hardware-Mixed Stereo secondary buffers.

Flag Name: DSCAPS_SECONDARYSTEREO


PrimaryBuffers
Number of primary buffers supported. This value will always be 1 for DirectX 3.


MaxHwMixBuffers
Specifies the total number of buffers that can be mixed in hardware.


MaxHwStaticBuffers
Specifies the maximum number of Static sound buffers.


MaxHwStreamBuffers
Specifies the maximum number of Streaming sound buffers.


TotalHWMem
Size, in KiloBytes, of the amount of Memory on the sound card that stores Static sound buffers.


MemoryTransferRate
Description of the rate, in Kilobytes per Second, at which data can be transferred to Hardware Static sound buffers (those located in On-Board Sound Memory).


CPUOverhead
Description of the Processing Overhead, as a Percentage of the Central Processing Unit, needed to Mix Software buffers (those located in Main System Memory). This varies according to the bus type, the processor type, and the clock speed.

MinRate
Minimum Sample Rate Specifications that are supported by this device's Hardware Secondary Sound Buffers.


MaxRate
Maximum Sample Rate Specifications that are supported by this device's Hardware Secondary Sound Buffers.


ContinRate
The device supports all sample rates between the Minimum Secondary Buffer Sample Rate and Maximum Secondary Sample Rate values. Typically, this means that the actual output rate will be within +/- 10 hertz (Hz) of the requested frequency.

Flag Name: DSCAPS_CONTINUOUSRATE
