snd_sbc, snd_sb16, snd_sb8 — Creative Sound Blaster ISA and compatible bridge device driver


To compile this driver into the kernel, place the following lines in your kernel configura‐ tion file: device sound device snd_sbc device snd_sb16 device snd_sb8 Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5): snd_sbc_load="YES" snd_sb16_load="YES" snd_sb8_load="YES" Non-PnP cards require the following lines in device.hints(5):"isa" hint.sbc.0.port="0x220" hint.sbc.0.irq="5" hint.sbc.0.drq="1" hint.sbc.0.flags="0x15"


The snd_sbc bridge driver allows the generic audio driver sound(4) to attach to Creative Sound Blaster ISA (mostly SB16 or SB8, known as SoundBlaster Pro) compatible audio cards. 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.


The snd_sbc driver supports the following sound cards: · Avance Asound 110 · Avance Logic ALS100+ · Avance Logic ALS120 · Creative SB16 · Creative SB32 · Creative AWE64 · Creative AWE64 Gold · Creative ViBRA16C · Creative ViBRA16X · ESS ES1681 · ESS ES1688 · ESS ES1868 · ESS ES1869 · ESS ES1878 · ESS ES1879 · ESS ES1888
