I'm attempting to write a very simple OS in ASM and C. (NASM assembler) I would like to access the sound card directly, with or without drivers. If I don't need drivers, how could I access and send a sample audio file to the sound card? (An example would be nice) If I do need drivers, is there anyway to interface them and call functions from the drivers? And how do I access and send a sample audio file to the sound card? (Another example would be nice)
What sound card? Do you have access to the register map of the card?
