To extend the audio hardware supported by DOSSound, there is also support for Soundblaster cards and their emulations. DOSSound first checks whether a soundblaster card is installed. If this is the case it will use that and not check for AC'97 controllers. It uses I/O address 220h, interrupt 7, and DMA1 for 8bit and DMA5 for 16bit operation. The interrupt used can be changed by the command line option /I5 to interrupt 5.
