FreeBSD supports the SoundBlaster, SoundBlaster Pro, SoundBlaster 16, Pro Audio Spectrum 16, AdLib and Gravis UltraSound sound cards. There is also limited support for MPU-401 and compatible MIDI cards. Cards conforming to the Microsoft Sound System specification are also supported through the pcm driver.
NOTE This is only for sound! This driver does not support CD-ROMs, SCSI or joysticks on these cards, except for the SoundBlaster. The SoundBlaster SCSI interface and some non-SCSI CDROMS are supported, but you can't boot off this device.
