All are capable of 8- and 16-bit audio sample +recording and playback at rates up to 44.1kHz. +.Pp +The AudioDrive takes 16 I/O ports. The I/O port range, IRQ, and DRQ +channels are set by the driver to the vaues specified in the +configuration file (or for isapnp or ofisa, the values assigned from +the firmware). The I/O port base must be one of 0x220, 0x230, 0x240, +0x250. The IRQ must be one of 5, 7, 9, 10 (or 15 on the 1887 +only). The first DRQ channel must be selected from 0, 1, 3. The second +DRQ channel (used for playback by the full-duplex 1888/1887, ignored +by the 1788) can additionally be set to 5. If both DRQ channels are +used they must be different. +.Pp +The joystick interface (if enabled) is handled by the +.Xr joy 4 +driver. +.Sh BUGS +The AudioDrive devices have a SoundBlaster compatibility mode, and may +be detected by the SoundBlaster driver (see +.Xr sb 4 ) +rather than the AudioDrive driver. The workaround is to remove the +SoundBlaster driver from the kernel configuration. +.Sh SEE ALSO +.Xr audio 4 , +.Xr isa 4 , +.Xr isapnp 4 , +.Xr joy 4 +.Sh HISTORY +The +.Nm +device driver appeared in +.Nx 1.4 . |
