The '056747' is another hybrid audio module found on Konami PCBs of the 90s.It shares the same ceramic package of the "brothers" '054986A' and '054544' :
But it has a different design of the analog circuit (the '054321' ASIC is still present as 'core' of the digital circuit).Personally I've seen it only on few PCBs like Run & Gun, Gaiapolis, Monster Maulers :
Although the different design his functionality is exactly the same of the '054986A' so both are fully interchangeable.I thought it was a good thing to reproduce it in order to have another replacement option for these such a fragile parts :
