Line 60: There are two modes for transfering data. First is single mode - data from buffer are played, interrupt is fired and playing is stopped. It make lower quality of sound. Second is auto mode - data from buffer are playing forever and interrupt is fired after play buffer. You should use interrupt for re-filling buffer. ~~==Detecting DSP==~~ Detecting DSP is really easy. You must send to DSP reset port 1, wait 3 microseconds, send to DSP reset 0 and read DSP read port. If in it is 0xAA, DSP exist. Some SB-compatible cards returned 0xAA on first check but on second check they reported their specific version. ==Playing sound==
