Remarks

Each entry is a full PropertyKey - a property-set GUID plus the PID that selects one property within that set. The PID is what distinguishes the members of a set: every PKEY_AudioEndpoint_* key below shares one fmtid and differs only in its PID, so a lookup that matched on the GUID alone could not tell them apart.
