Hi Peter. Firstly this is probably going to be of no help, as I don't have any
laptops, and my Sarge, Etch, and Lenny installs are on a machine which has a
well supported Creative Audigy2 soundblaster card. That said, perhaps you
could provide a bit of info.
leaving aside your Sid install on the Toshiba 4000CDS, Which kernels do you
have available on your IBM NetVista machine. All my Debian installs were
initially installed from Woody 3.0r2, and I have a bunch of kernels
available, some of which are pre udev, For example on my Lenny install, I
have the following kernels available.
2.6.8
2.6.11
Both these IIRC are pre udev, and you should have no problems running alsaconf
when booting with these, and whatever alsaconf configures, should be saved
over a reboot.
I also have 2 kernels which I believe use udev, and sound still works ok in my
case, as below.
2.6.17
2.6.21
Which kernel is your Lenny using? uname -r will give you this.
Now I may be wrong here, but seem to have read that you shouldn't run alsaconf
on kernels that are supposed to be setting up Alsa via udev, as it may mess
some stuff up. As you say though that running alsaconf gets the sounds going,
this may confirm that I'm wrong on this.
Do you have an earlier kernel available to try, perhaps a 2.6.8, or 2.6.11, as
I have?
When you bootup the IBM NetVista machine with Lenny on it, what do you get
from the following commands.
lsmod | grep snd
cat /proc/asound/version
cat /proc/asound/cards
and
lspci -v (just the bit for the soundcard will do here)
and perhaps, after running alsaconf, the output of.
lsmod | grep snd
cat /proc/asound/cards
That's all I can think of at the moment, and may not be much help in resolving
your problem.
Nigel.

Alsaconf & halting a frozen laptop.
Nigel,
Progress!
SUMMARY
According to the outputs from lsmod below, the net
effect of alsaconf is to remove snd_hda_intel. So,
unless there is more specific advice, I should find how
to prevent loading of snd_hda_intel at startup.
Odd that removing snd_hda_intel makes sound work!
Thanks, ... Peter E.
nh> Which kernel is your Lenny [on IBM NetVista] using?
Currently only 2.6.25-2.
nh> Do you have an earlier kernel available to try, perhaps a 2.6.8, or 2.6.11
I can install one of them if necessary.

Hi Peter. Interesting from viewing the lsmod output below, that both
snd-hda-intel, and snd-intel8x0 are being loaded, and also very weird.
You should be able to just blacklist the snd-hda-intel module
in /etc/modprobe.d/blacklist, but I've seen some folks having problems
blacklisting modules, as they still seem to load.
I'd suggest adding a line to /etc/modprobe.d/alsa-base, as below.
install snd-hda-intel /bin/true
Any module loaded into /bin/true goes to nowhere land. It's loaded, but does
nothing, and is effectively sent into limbo.
There is clearly some sort of conflict going on when both snd-hda-intel,
snd-intel8x0 are being loaded, so that neither is detected as a sound card
in /proc/asound/cards, and only your usb headphone set is detected, and set
as card0 as no other cards can be found.

See how it goes with my suggestion above.
Nigel.
Really weird though, like the modules have been smoking some dodgy stuff, and
both insist on being the one for the soundcard.

I had the same problem with via82 which conflict with cmipci module.
When I unload via82 module, sound work again. Why my cmi sound card and
my via82 chipset sound can't work both ? I don't know.
So I had to blacklist it with its dependencies since it keep loading if
I just blacklist via82 module. I added 3 lines
to /etc/modprobe.d/blacklist :
# Blacklist via soundcard
blacklist snd_via82xx
blacklist snd_ac97_codec
blacklist ac97_bus
