HD Install :: Sound not working



It could be that your sound card is muted - if you use the alsamixer command from a terminal window, you should be able to check this from the volume/mute controls that appear.

i  tried with all the alsa packages in the repository. they are installing fine but still sound cannot be heard even at very high volumes though alsamixer when run returns the error message "failed to load... default" something like that.



i have said this too...



dont know what may be the reason for the error too. does sound anyway related with the kernel version???



i dont know the concept but my sound was working with ubuntu without any configuration ( it also uses alsa but with kernel 2.6.x).  possibly i may post required info detecting my sound card provided i need the path of that files which has info on my sound card.
Maybe you could post the output of "lsmod" after alsa is loaded and also the output from "lspci" (or "lsusb") relevant to your soundcard. I think the alsa sound card info is in /proc/asound or something like that.

Perhaps alsamixer is not included in the alsa extension - you could get it from the Knoppix 3.4 CD.
which alsa extension output i could post...



there are many packages here in repo..

alsa4dslv2only.dsl
alsadebs.dsl
ALSA 1.011Xxx.dsl
alsa.dsl

which i could use now from here for o/p as im using dsl 2.1 only now ......
I would suggest booting DSL with the "nosound" and without the "alsa" boot options. Once booted, use "lsmod" to check that there are no OSS (eg AC97 or similar) or snd-xxx modules loaded. If there are any sound modules loaded, remove them with "rmmod -f module_name" (sometimes you have to use the command more than once) - do not remove the soundcore module.

Next load the alsa.dsl extension from the system section of the repository and use the right-click menu to initialise it. Check using "lsmod" to see if the alsa modules are loaded, you should see something like this.

soundcore              11104  1 snd


You could also check in /proc/asound (or whatever it is).

If everything looks OK up to this point, I would suggest getting hold of alsamixer to see what comes up.
