The PKEY_AudioEndpoint_JackSubType property contains an output category GUID for an audio endpoint device. The header file Ksmedia.h defines the GUIDs; each GUID specifies the type of connection. These GUIDs also have associated pin categories. For example, header file Ksmedia.h defines the GUID KSNODETYPE_DISPLAYPORT_INTERFACE for a display port that connects with the KS pin defined by the GUID PINNAME_DISPLAYPORT_OUT.
For more information, see the description of pin category properties in the Windows DDK documentation.
The vt member of the PROPVARIANT structure is set to VT_LPWSTR.
The pwszVal member of the PROPVARIANT structure points to a null-terminated, wide-character string that contains a category GUID.
