remember boot -c? thats how ya used to diddle sound cards to get them
probed properly. With the ELF boot loader, that has all changed.
Im assuming the bios attached it fine but freebsd didnt attach it to
the pcm driver.
in /usr/src/sys/i386/isa/snd/CARDS is a list of sound cards and values
for the boot loader to get the PnP controller to attach it properly.
Yours may already have a working definition in there. Here's the long
answer anyway....
if you use pnpinfo(8) it will tell you what your card wants for a
config:
Checking for Plug-n-Play devices...
Card assigned CSN #1
Vendor ID CSC7537 (0x3775630e), Serial Number 0xffffffff
PnP Version 1.0, Vendor Version 2
Device Description: Turtle Beach Malibu
Logical Device ID: CSC0000 0x0000630e #0
Device Description: WSS/SB
TAG Start DF
Good Configuration
DMA: channel(s) 1
8-bit, not a bus master, count by byte, , Type A
DMA: channel(s) 0 3
8-bit, not a bus master, count by byte, , Type A
IRQ: 5 - only one type (true/edge)
I/O Range 0x534 .. 0x534, alignment 0x4, len 0x4
[16-bit addr]
I/O Range 0x388 .. 0x388, alignment 0x8, len 0x4
[16-bit addr]
I/O Range 0x220 .. 0x220, alignment 0x20, len 0x10
[16-bit addr]
<less optimum configs snipped>
my particular card wants:
pnp 1 0 os enable port0 0x534 port2 0x220 irq0 5 drq0 1 drq1 3
the above line goes in your /kernel.confg file, sourced from /boot/loader.rc
habanero$ cat /boot/loader.rc
load /kernel
load -t userconfig_script /kernel.config
load -t splash_image_data /rose.bmp
load splash_bmp
autoboot 5
habanero$ cat /kernel.config
pnp 1 0 os enable port0 0x534 port2 0x220 irq0 5 drq0 1 drq1 3
( watch out for stepping all over ports and irqs and stuff that other
peripherals might be using )
which on boot should produce output something similar to:
CSN 1 Vendor ID: CSC7537 [0x3775630e] Serial 0xffffffff Comp ID: @@@0000 [0x00000000]
mss_attach <CS4237>1 at 0x530 irq 5 dma 1:3 flags 0x13
pcm1 (CS423x/Yamaha/AD1816 <CS4237> sn 0xffffffff) at 0x530-0x537 irq 5 drq 1 flags 0x13 on isa
and
pcm0 not found
[because it attaches the device at pcm1]
Now. Since the pcm driver attached the car at 1 instead of 0, the
links to /dev/{audio,dsp,mixer} need to be adjusted from /dev/audio1
instead of /dev/audio0. Same for mixer0 and dsp0. Change them to 1.
habanero$ ls -la /dev/{mixer,dsp,audio}
lrwxr-xr-x 1 root wheel 11 Sep 13 1998 /dev/audio -> /dev/audio1
lrwxr-xr-x 1 root wheel 9 Sep 13 1998 /dev/dsp -> /dev/dsp1
lrwxr-xr-x 1 root wheel 11 Sep 13 1998 /dev/mixer -> /dev/mixer1
hope this gets ya goin!
