Hi Peter,
The 2.4 & 2.6 kernels use different, incompatible module formats, so
you can't just copy
the 2.4 modules over to 2.6. Instead you will need to install a 2.6
kernel module for your
soundcard. If your kernel was already configured to build your
soundcards drivers as
modules, all you should need to do is cd /usr/src/linux (or where ever
you 2.6.7 kernel
sources are); make modules && make modules_install. Note that make
modules_install
needs root permissions. Also also note that 2.6 normally uses ALSA
(Advanced Linux
Sound Architecture), while 2.4 used OSS (Open? Sound System). This
means that you
soundcards driver module might have a different name, so you might
need to edit the
module name in /etc/modules.conf or where ever you define modules to
load on startup.
After this you should be able to load your soundcards driver modules &
hear stuff.
HTH,
Conway S. Smith

Kernel 2.6 structure is different to 2.4 for modules, sound modules reside in
kernel/sound and not kernel/drivers/sound.

Not a good thing to do, 2.6 kernels are "very different" to 2.4.

You will need to check your /usr/src/linux/.config file to see what you have
defined for sound.
Go here;

For good info on compiling 2.6 kernels.

Even 11 seconds sounds way to long, but you did not say what sort of computer
it is, let alone how much memory you have, etc etc etc...

Probably worth running alsamixer just to check it's not as simple as
everything being muted before you look deeper for the cause of your problems.
If not, you'll want to unmute everything after completing the steps to make
it work.
You'll want to check your kernel compile options to make sure you're compiling
your sound drivers (preferably as modules), you'll also find that between
kernel 2.4 and 2.6 there is a change from OSS to ALSA as the primary sound
architecture.
www.alsa-project.org will be able to tell you what you'll need to know.
You'll want to add a line similar to this to your modprobe.conf file.
alias snd-card-0 snd-via82xx
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx
&& /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-via82xx { /usr/sbin/alsactl store >/dev/null 2>&1
|| : ; }; /sbin/modprobe -r --ignore-remove snd-via82xx
The extra lines will load and save the mixer settings for ALSA, the above has
been taken from my modprobe.conf file.
You also might want to run alsamixer and just check that your sound isn't just
muted. After the above steps you will still need to unmute your sound card
anyhow.
