1. More on sound.
My little SB16 doc says i should do the following:
-----------
To record or play back sound, you should use the following sequence:
1) Allocate a buffer that does not cross a 64k physical page boundary
2) Install an interrupt service routine
3) Program the DMA controller for background transfer
4) Set the sampling rate
5) Write the I/O command to the DSP
6) Write the I/O transfer mode to the DSP
7) Write the block size to the DSP (Low byte/High byte)
-----------
What should the interrupt actualy do? do i realy need it?
Also, what is the IRQ used for?
-Mark.
