NAME    [Toc]    [Back]

     sbc -- Creative Sound Blaster ISA and compatible bridge device driver

SYNOPSIS    [Toc]    [Back]

     device sbc

     Non-PnP cards require the following lines in /boot/device.hints:
     hint.sbc.0.at="isa"
     hint.sbc.0.port="0x220"
     hint.sbc.0.irq="5"
     hint.sbc.0.drq="1"
     hint.sbc.0.flags="0x15"

DESCRIPTION    [Toc]    [Back]

     The sbc bridge driver allows the generic audio drivers including pcm(4)
     to attach to the following ISA sound cards:

     +o	 Creative SB16, SB32, SB AWE64 (including Gold) and ViBRA16

     +o	 Advance Asound 100, 110 and Logic ALS120

     +o	 ESS ES1868, ES1869, ES1879 and ES1888

     The value of flags specifies the secondary DMA channel.  If the secondary
     DMA channel is C, set the flags to (C | 0x10). For a sound card without
     the secondary DMA channel, the flags should be set to zero.

DIAGNOSTICS    [Toc]    [Back]
