Summary: get sound module working
Some time ago I posted a question about getting sound to work on my
Tecra 740CDT. After some hints from Patrick Wiseman and a lot of digging
and the Modules and Sound HOWTOs, I found the actual steps for loading
the kernel module pretty easy. I want to share this and encourage the
others of the above mentioned documentation to take note.
1) Find out what kind of sound hardware you have. It may be in the manual.
It may be in documentation for your computer at the manufacturer's
website. I found mine at http://www.cck.uni-kl.de/misc/tecra710/.
It is the CS4232 chip set.
2) Find out what ports and interrupts your computer is using for the sound
device. You should be able to find this in the BIOS. On my Toshiba,
I get into the BIOS setup program by holding ESC while the computer
reboots. (If it isn't there, try to get a technical manual for your
computer from the manufacturer's website.)
3) Find out which hardware module you need. In my case it was simple:
/lib/modules/2.2.17/misc/cs4232.o was pretty obvious. The Sound HOWTO
has pretty extensive information. I've been told that the ALSA driver
(opl3sa2.o) is pretty general.
4) Find out what parameters the module needs. This was the stumbling
block for me.
# modinfo cs4232
parm: io int
parm: irq int
parm: dma int
parm: dma2 int
parm: mpuio int
parm: mpuirq int
parm: synthio int
parm: synthirq int
5) Run modconf to select the driver, choose to load the module, and
specify the parameters. In my case:
io=0x534 irq=5 dma=1 dma2=0 mpuio=0x330 mpuirq=5 synthio=388
(Note, using modconf instead of insmod ensures you get any other
supporting modules you need.)
There may be other stumbling blocks for other folks, but the above should
be a pretty good path to try first.
