How to enumerate DirectSound DirectX Media Objects (DMOs) on your system

Source and binaries (amd64 and x86) attached.

Pseudocode:

GUID dmo_categories[] = { ... }
for (each guid in dmo_categories) {
   IEnumDMO = DMOEnum(guid, DMO_ENUMF_INCLUDE_KEYED, ...);
   while (0 != items fetched by IEnumDMO::Next(&iid, &szName...)) {
      print iid, szName
   }
}

Output on my system:
