Re: YAMAHA OPL-SAx3 Sound Card Configuration Problem

[Naren A Devaiah <naren@xxxxxxxxxxxxxxxx>]

Well, I do have a OPL SAX card and it works for me ! Both under 2.0.x as
well as 2.2.7.. but I use slackware....anyways here's how I got it to work
in 2.0.x.

In both cases I had to recompile the kernel...If you are desperate enuff
to hear sound, then I guess U might try ur hand at this!

For 2.0.x
- ---------
I got this to work as a Crystal CS4232 card (I found this by checking the
Windows driver!)

1. As root, make menuconfig
2. select Sound->Crystal CS4232 (My PnP card worked with the sound driver
   compiled into the kernel..and I turned off the 'PnP OS option in my
   BIOS setup...dunno how much that helped tho..coz the PnP card worked
   even with that setting being 'ON'. But I figure that setting it to 
   'OFF' tells the BIOS to initialize the card, instead of expecting the
   OS to do it... but I might be off-track on this aspect!) 
3. Check the irq/dma/io values for your card (on mine io=0x534, irq=5,
   dma=0,3)
4. Select MIDI (if you want that)
5. Recompile the kernel and reconfigure/rerun lilo etc...
6. Boot and check if 'cat /dev/sndstat' produces the expected output
   (instead of blank fields)

For 2.2.x
- ---------

The sound driver has to be built as a set of modules... doesn't seem to
work if compiled into the kernel...(somethings work, but then
functionality is really limited!)

1. make menuconfig
2. Select Sound->OSS modules   (Select sound as a MODULE)
3. Select the OPL-SA2/SAX driver...
4. Rebuild the kernel
5. Read /usr/src/linux/Documentation/sound/OPL3-SA2 doc...This gives you a
   way of loading the module (which worked for me!).. The actual command
   line I use is given below (in my rc.modules)

  /sbin/modprobe opl3sa2 io=0x370 mss_io=0x530 mpu_io=0x330 irq=5 dma=0 dma2=3
  /sbin/modprobe opl3 io=0x388  (this is for MIDI)
6. Add these lines in your init scripts (U may have to change a few
   values...irq for instance for your particular card)
7. Reboot the new kernel and check the /dev/sndstat output

Now your sound card should work!
