Hi,

I've got an IBM T23 (with Intel 82801 sound controller) everything is OK but i couldn't have sound working out of the box. Has someone found a way to get it work?
Thanks.

In Linux there are two families or type sound drivers: ALSA and OSS drivers.
DSL install by defect OSS type driver.
Frequently the sound problems is the resources assignation (irq, dma, port) for the sound controller.
I do not know which is the driver for your chipset but you can do this:

-Make sure your bios is set for PnP OS = NO

-Check if driver module for the 82801 sound controller was loaded doing the command:
lsmod

-Check interrup comflicts doing the command:
cat /proc/interrupts

-Remove and Reload again the driver module specifying the resource assignation.

- Try utility sndconfig. I explained that here:
http://damnsmalllinux.org/cgi-bin....t=12929

Other possibility:
Newer cards may need ALSA diver

You could try to use the ALSA driver but booting from Live DSL CD so, if you have installed DSL to hard disk, you not will modify your actual configuration for OSS driver .
Procedure:

1. Boot from DSL CD

2. Install the 3 following MyDSL extensions:

-gnu-utils.dsl
-dsl-dpkg.dsl
-If your DSL is v2.0 or v2.1 then install alsa.dsl, else install alsadebs.dsl. (Importante: Choose the correct file for your DSL version or the ALSA driver not will work)

3. Execute the script ALSA install by go to MyDSL -> ALSA menu.

4. Try play sound

Thanks Picolo,

my sound card is detected and the modules are loaded:
lsmod |grep audio returns:
i810_audio 36884 0
ac_97_codec 20108 1 i810_audio
soundcore 11104 2 snd,i810_audio

but a 'cat /dev/sndstat' returns no such file or directory

I installed alsa (mydsl package) alsaconf went ok (it detected the audio controller) but when i ran alsamixer i get: function snd_ctl_open failed for default : no such file or directory

i checked irc in /proc/interrupts, and i noticed my sound card (i8042) is present on irq 1 and on irq 12.i'll take a look in BIOS settings of the laptop...
strangely, it's a new laptop i got (with windows xp pre-installed on it, and sound is ok on XP...
Any way, thanks for the advice
