Hi,

Im trying with DSL 2.1 on my PC (AMD SEMPRON 1.6 GHz) having VIA 82Cxxxx sound card (detected like this by DSL: Realtek AC97 audio). Im using DSL 2.1 since it has SATA support for my harddisk.I cannot hear sound. So i downloaded and installed 'sndconfig' using apt-get and then also it failed. It is reporting simply as 'An error occured'. Also i tried using ALSA for DSL 2.0 and 2.1 mydsl package. It is also failing. I dont know how to use modprobe. Please help configuring sound......

If sound is working i can have fully working DSL installed....

If you didn't do it already, it would be a good idea to go to the ALSA site and check if your card is supported. There is a VIA southbridge AC97 audio VIA82C686 using the ALSA snd-via82xx driver that sounds (sic) like it might work.

If your card is supported, you have the choice between using the sound drivers in 2.4.31 (OSS) or the ALSA drivers. If you want to use the ALSA drivers, I've found you need to remove any sound drivers, except "soundcore", that might be installed before you try the ALSA drivers. I believe the latest ALSA extension in the repository should work for you (gnu-utils also needs to be loaded?) and should load the required drivers automatically.

If you want to try the OSS drivers, you might want to check that DSL loaded the correct ones first. If you have the correct driver, you might also need to pass some parameters like the correct IRQ and DMA settings to use with the driver for your soundcard.

i booted dsl 2.1 in

dsl sata,alsa

it booted fine .

then i loaded gnuutils.dsl from repo..

then 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 think sound configuration is done using alsaconf.

it is available in only alsa4dslv2.dsl package .

i installed that and it is not displaying any via drivers. so it fails on running.

i also downloaded the "alsadrivers/alsaconf" package from the alsa site ( there are lot of files there and im confused what to download- i think these are the right ones) and tried to install them with gccxx.dsl(with libs) package. but it fails in ./configure step itself.

also in some places (during install as well as configure) it returns "chown: not owned by root"

i dunno wat to do after this.

i tried running

sudo apt-get install alsa-utils

something like that. they are also failing

i also dunno the IRQ DMA parameters/ modprobe details.....

probably i can give information on the files which detects my sound card ( i dunno what are those files but can post if required provided giving me the path for those files in DSL live CD) and possibly with that it could be said what can be done for that...

Just to double-check - when you install the most recent alsa extension, I believe it is a two part process:

1. You install the extension
2. You select "install alsa" (or something like that) from the right-click menu

As well as installing the correct drivers, the second part creates a bunch of entries in /dev which allows your sound card to work.
