Size is the amount of memory in bytes. The documentation is incorrect. Thanks
for the heads-up, I have filed a bug internally.
* I need more than 32k of memory
Call AERT_Allocate multiple times until you have enough memory. Be aware that
nonpageable memory is a precious resource, so only allocate as much as you
need. The memory you get from successive allocations may be noncontiguous; you
will need to handle this case when you are using the memory.

Subject: [wdmaudiodev] AERT_Allocate in an sAPO
According to the documentation I MUST use AERT_Allocate for memory allocation
when developing an sAPO:
https://msdn.microsoft.com/en-us/library/windows/hardware/ff536213(v=vs.85).aspx
So I have two questions:
1. According to the documentation of HRESULT AERT_Allocate(size_t size, void
**pMemory);
Size is the number of input connections – what does that even mean? Is it not
the amount of memory in bytes?
1. I get an error when allocating more that 32k of memory using
AERT_Allocate??? I need more that 32k of memory. What to do?
I see that this question has been asked before, but never answered:
