how use sound cards? how use sound cards? SirShahzad (Instructor) (OP) 27 Jan 01 17:43 how can we use sound cards in C or C++ programs. for wave filles or games etc. RE: how use sound cards? Nosferatu (Programmer) 28 Jan 01 14:14 Well, you should use some low level C functions like outp and inp (out port and in port) along with the documentation of the specific soundcard.Usually you write some data on some specified port (outp) to request some information -inp- (alot of "some's")... In this way you can obtain the input-output range, the usable IRQs and DMAs. Of course, this is usable in non-windows applications, as far as i know. If you're using WinAPI, there are specific functions to play a wave file which will spare you of all the work in finding out the above parameters.
