Well, the getting the audio to work is proving harder than I expected,
so I am canvasing suggestions if any gurus out there have any ideas..
The situation is as follow:
1. I know the hardware works, and works with Linux, because I still have
my old SuSE 7.3 sitting in a partition and can boot and play audio
from it. The module it uses are listed in my original post below.
2. If I run 'alsaconf' on my 2.6 kernel I get
Unloading ALSA sound driver modules: (none loaded).
Building card database...
Searching sound cards (and a progress bar..)
No supported PnP or PCI cards found
Would you like to probe legacy ISA sounds cards/chips?
which is expected as the OPL3 is not PCI or PnP.. so I answer 'Y'
Probing lagacy ISA cards may make your system unstable. Y
Please select the drivers to probe:
x [*] opl3sa2 Yamaha OPL3SA2+ x
x [*] cs4236 Cirrus Logic CS4235-9 x
x [*] cs4232 Cirrus Logic CS4232 x
x [*] cs4231 Generic CS4231 x
x [*] es18xx ESS ES18xx AudioDrive x
x [*] es1688 ESS ESx688 AudioDrive x
x [*] sb16 Sound Blaster 16 x
x [*] sb8 Sound Blaster 1.0/2.0/Pro
I select the first entry only....
x Shall I try all possible DMA and IRQ combinations? x
x With this option, some unconventional configuration x
x might be found, but it will take much longer time.
I answer 'Y'
Probing legacy cards.. This may take a few minutes..
Probing: opl3sa2
then after quite a long delay....

mqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqj
then I am back to my prompt, which seems a little inconclusive, but
I think it means it didn't find anything. There is no sign of anything
having changed (no modules loaded), and /var/log/kern.log contains:
Jan 26 17:33:48 localhost kernel: Yamaha OPL3-SA soundcard not found or
device busy
Jan 26 17:34:19 localhost last message repeated 36 times

Jan 26 17:41:24 localhost last message repeated 70 times
Jan 26 17:41:51 localhost last message repeated 30 times
3. I discovered that if I reboot to the 2.4 Sarge kernel and
try the 'alsaconf' again, alsaconf does succeed in detecting
the hardware - which made me think that it might be a 2.6
kernel issue. But after the alsaconf finished, the audio still
didn't seem to be working. The only files created in /dev
which were group 'audio' were:
/dev/snd/controlC0
/dev/snd/timer
/dev/rtc
4. Richard's suggested additions to /etc/modules did result in a
reasonable looking list of loaded modules, but no audio devices
appear in /dev.. I did check the BIOS and confirmed that my settings
matched his.
So if anyone has any ideas of things I could try which might
shed some light on the reaosn for the problem, please let me
know....
