alsa/sound on thinkpad
Dear All
Thanks for comments. However, sound still not working.

"This might be one of those instances where you just go ahead and compile
the ALSA modules from source against your 2.4.18 kernel, which I have
done here. In the kernel config you must compile sound support as a
module, but do not enable any other sound drivers. In other words, if
you do a make menuconfig, select sound support as <M> module and leave
all other sound selections blank."
I recompiled the kernel and compiled alsa from source, as per this
suggestion and the instructions in the respective packages. The resulting
alsa-modules required alsa-base before it would install, so I installed
that. After a reboot I ran alsactl, to un-mute the mixer channels. Alsactl
failed with the error message, "No ALSA drivers installed." As I thought
I'd just installed Alsa, I am at a loss again. Do you install the drivers
separately from installing the modules?
Running alsaconf failed with the same messages as before (can't locate
module snd; No ALSA driver installed; etc.). Why is it looking for module
snd? Would it help if I could tell it to look for module 'sound' - how
would I do that?
Here are some relevant-looking lines from /var/log/messages of a recent
bootup:

Alas, kudzu added only the following to my modules.conf:
### update-modules: start processing /etc/modutils/kudzu

This looks like a good lead, but unfortunately I don't quite know how to
make use of it. 'man modules.conf' is not enough!
So - I thought I'd installed alsa from source but some crucial step seems to
have been missed - don't know what. Also module configuration is quite
different from that of a known-working similar machine - don't know how to
fix that either.
Sorry I haven't got clear questions this time: any clues or prompts for more
info will be gratefully received and acted upon.
I should say I'm not as newbie as I probably sound. I've been using Linux
for a few years now but ,after a brief stint on Caldera OpenLinux 2.4 I've
been using SuSE since 6.4. I decided to switch to Debian when I realised
that SuSE's 'user-friendliness' was allowing me to understand less and less
of what was actually going on. This just felt bad, and it was removing one
of the main things attracting me to free software in the first place.
However, I am clearly still in the process of weaning myself off the GUI and
the nanny distro.
Best wishes
Ivan
