Splinter Cell and Splinter Cell: Chaos Theory query for unsupported propset #102

Open Hiradur opened 1 month ago

Hiradur commented 1 month ago

Both Splinter Cell and Splinter Cell: Chaos Theory query for a propset that DSOAL reports as unsupported:

0024:debug:dsound:BufferProp::QuerySupport (087c3a28)->({a94047c0-1cef-11d3-bdb8-00c0f02ddf87}, 0x0, 0032d0d8)
0024:fixme:dsound:BufferProp::QuerySupport Unhandled propset: {a94047c0-1cef-11d3-bdb8-00c0f02ddf87} (propid: 0)

Quote from @kcat after mentioning this on IRC:

[13:28:45] <KittyCat> hmm, I wonder what that guid is. it seems similar to DSPROPSETID_EAX30_ListenerProperties/DSPROPSETID_EAX30_BufferProperties, but not quite the same
[13:30:03] <KittyCat> neither the wine or eax headers seem to have it, a search isn't showing anything promising
[13:31:03] <Hiradur> Could it come from DS3D or be specific to Creative's driver?
[14:03:28] <KittyCat> maybe Creative's driver, or some unknown/under-documented eax interface

Interestingly these, fc2, ac and BGE are all first party ubisoft games.. Ok nvm max payne 2 should also have it. Could it be a query for EAX1 properties?

It might be provided by an EAX implementation from one of Creative's competitors. IIRC, Realtek and Aureal provided their own EAX implementations and possibly others as well.
