Hello. I am trying to get my OPTi 931 working under 3.4-RELEASE with
GNOME and Enlightenment.
I've read the handbook and the pcm(4) man page. I think I need more
information.
In the section under OPTi, I find the following line which is repeated in
the handbook and the pcm(4) man page:
---file:/usr/src/sys/i386/isa/snd/CARDS---
PNP CONFIG:
pnp 1 1 os enable port0 0x534 port2 0x220 port3 0xe0d irq0 10 drq0 1 drq1 6
---file:/usr/src/sys/i386/isa/snd/CARDS---
But this isn't working for my kernel. I always get a "config: line 174:
syntax error" on this line.
I booted another machine with the card in it and found out that mine is
set as follows:
Audio:
I/O address: 530h
IRQ 5
DMA Playback 1
DMA Record 0
MPU-401: (enabled)
I/O address: 330h
IRQ 2/9
DMA buffer size: 16
My dmesg currently says:
---from dmesg---
Probing for PnP devices:
CSN 1 Vendor ID: OPT0931 [0x3109143e] Serial 0xffffffff Comp ID: @@@0000 [0x00000000]
This is an OPTi931, but LDN 1 is disabled
Probing for devices on the ISA bus:
---end dmesg---
I have tried "boot -c" to no avail.
I can't find the configuration floppies or the files to download to config
the card anywhere. :/ I think I would be doing better if I knew what each
individual option in the pnp line above meant. What does "os enable"
mean/do? What does port0 refer to? Should I change the 0x534 to 0x530 to
match my card's config?
Now, not being exactly clear on what all the options in that pnp line
mentioned above meant, I tried the following in my kernel:
--- from MYKERNEL ---
controller pnp0 # PnP support for ISA
controller isa0
controller eisa0
# SoundCard Support
pnp 1 1 os enable port0 0x534 port2 0x220 port3 0xe0d irq0 10 drq0 1 drq1 6
--- end MYKERNEL ---
without much luck. This is the only ISA card, the only PNP card, and the
only EISA card in my system. So, can I leave off the "controller pnp0"
line? Will the "pnp 1 ..." line suffice?
I also find some confusing language in the handbook:
---file:/usr/share/doc/en/books/handbook_3.3/kernelconfig-config.html---
To include sound card support, you will have to copy the appropriate lines
from the LINT kernel (which support for every device) as follows:
controller snd0
Generic sound driver code. Required for all of the following sound
Hello. I am trying to get my OPTi 931 working under 3.4-RELEASE with
GNOME and Enlightenment.
I've read the handbook and the pcm(4) man page. I think I need more
information.

...
controller pnp0 # PnP support for ISA
controller isa0
controller eisa0
#
# SoundCard Support

cards except pca and pcm. ... device pcm0 at isa? port ? tty irq 10 drq 1
flags 0x0
The pcm driver provides support for various ISA sound cards that are compatible with the WSS/MSS specs, or with the Sound Blaster Pro and
Sound Blaster 16.
Note: There is some additional documentation in /usr/src/sys/i386/isa/sound/ and /usr/src/sys/i386/isa/snd/. Also, if you add any of
these devices, be sure to create the sound device nodes.

It says that I need the snd0 for every card *but* pca & pcm but nowhere do
I see it telling me to insert the pcm line, only the pnp one!? I think I
can deduce that my card is pcm because a pnp instruction turns up for it
in the pcm(4) man page. Should I also have the pcm line given here?
Again, what sections of this line correlate to the configs I know about
the card?
This also hints that the WSS/MSS lines I'd seen around the files quoted
here might be applicable. Are they?
Finally, this last section I found was dated from August of last year, but
2.1 was long since gone even by then! Hopefully that's what the feature
freeze is all about. I'd like to help if I can, if the task is editing
the sections relevant to the OPTi card or just bringing this to light.
---file:/usr/src/sys/i386/isa/sound/sound.doc---
Instructions on using audio on a FreeBSD 2.1 (or 2.0-current) system.
See also /sys/i386/conf/LINT.
To enable sound driver support, the controller sound code must be included
in your config file:
# SB = SoundBlaster; PAS = ProAudioSpectrum; GUS = Gravis UltraSound
# Controls all sound devices
controller snd0
---end file:/usr/src/sys/i386/isa/sound/sound.doc---
I should also note that I did do:
cd /dev
./MAKEDEV snd1
already as root and it seemed a success. :)
Thank you for answering one or many of these questions and for helping me
out of my silence!
p.s. Is there anything special I should do to gnome or enlightnenment to
get the sound up in there? I'm excited to hear what it's like!
TIA!
