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.
