iam using dsl 2.1 version.

i tried wat u said.

booted with

dsl nosound option

but on loading alsa.dsl it does not list any modules related to sound except soundcore.

alsa.dsl created 2 commands namely alsa_init and alsa_snddevices. on running alsa_init it returns some error. I then loaded alsa4dslv2.dsl.

it also returned

"alsamixer: function snd_ctl_open failed for default: No such device" on running alsamixer.

also there is no file or dir named /proc/asound foound here.

wat could be the problem...

i am alo posting the o/p of some listings:

"lsmod" seems to confirm that no sound modules are loaded at boot and from "lspci", DSL seems to identify your soundcard correctly. The stdout messages seem strange though...

Maybe you could try the following from a terminal window as root to see if any error messages come up:

Code Sample

[boot with 'nosound" option]
# su dsl mydsl-load /path-to-file/gnu-utils.dsl
# su dsl mydsl-load /path-to-file/alsa.dsl
# /opt/alsa/alsasetup

What sort of DSL installation do you have - I see you're using 2.1 but is it a frugal hd install, classic hd install, USB boot or what? The reason I ask is that from the module not owned by root messages, it seems like there may be a problem with the file permissions.

In emelFM, if you highlight /lib/modules/2.4.31/kernel/sound/acore/snd.o, what does it say about the file permisions - root/root, dsl/staff, or?

I have HD installation only. The files in /lib/modules/2.4.31/kernel/sound/acore directory are owned by root only. no clue ..... or is it possible to update kernel manually to 2.6 and then install alsa using apt, if so pls give me the exact commands used there if u know.....
