Re: any Libretto 100/110CT users out there?



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  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....

               x                                                x               
               x                     <Ok>                       x               
               x                                                x

  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 17:35:20 localhost last message repeated 72 times
	Jan 26 17:36:21 localhost last message repeated 72 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....
