Information retrieved in the DSCAPS structure describes the maximum capabilities of the sound device and those currently available, such as the number of hardware mixing channels and the amount of on-board sound memory. You can use this information to fine-tune performance and optimize resource allocation.
Because of resource-sharing requirements, the maximum capabilities in one area might be available only at the cost of another area.
