34 .Nd Creative Sound Blaster ISA and compatible bridge device driver
36 To compile this driver into the kernel, place the following lines in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
43 Alternatively, to load the driver as a module at boot time, place the
46 .Bd -literal -offset indent
50 Non-PnP cards require a setting in the kernel config file:
51 .Bd -literal -offset indent
52 .Cd "device pcm0 at isa? port? irq 5 drq 1 flags 0x15"
57 bridge driver allows the generic audio driver
59 to attach to Creative Sound Blaster ISA compatible audio cards.
61 The value of flags specifies the secondary DMA channel.
63 DMA channel is C, set the flags to (C | 0x10).
64 For a sound card without the
65 secondary DMA channel, the flags should be set to zero.
69 driver supports the following sound cards:
107 .It sb_dspwr(XX) timed out.
108 A command to the DSP has timed out.
109 Check the I/O port configuration.
110 .It bad irq XX (5/7/9/10 valid)
111 The IRQ given to the driver is not valid.
118 device driver first appeared in
