Querying Auxiliary Audio Devices

Not all multimedia systems have auxiliary audio support. You can use the auxGetNumDevs function to determine the number of controllable auxiliary devices present in a system.

To get information about a particular auxiliary audio device, use the auxGetDevCaps function. This function fills an AUXCAPS structure with information about the capabilities of a specified device. This information includes the manufacturer and product identifiers, a product name for the device, and the device-driver version number.
