Greetings everybody!

I am new to both Linux and these forums, so do forgive me for my lack of knowledge in these matters. I have recently discovered the joy of Linux (via Ubuntu 11.10) and am now taking a look at various distros out there. SliTaz has impressed me very much so far.

From what I have gathered though, it seems like I am not the first to have sound issues with SliTaz, and while there seems to be a couple of threads on the matter, I fail to understand them or how they relate to my particular case. (Once again, remember that I am new at this! ^^')

Anyway. I am currently trying the LiveCD (SliTaz 4.0-RC3, Cooking) and failing to get any sound to work. I am on a Mac and MacOS X lets me play sounds without problems, so I figure that it's not my sound card per-say that is the problem.

When I run soundconf, I get the message "No supported PnP or PCI card found. Would you like to proble legacy ISA sound cards/chips?", and when I say Yes I am greeted with "No legacy drivers are available for your machine".

From what I can tell, my soundcard is a HDA Intel ALC889A.

With regards

Sound requires linux-sound , alsa-lib , alsa-utils
If those tazpkgs are installed:
Open terminal type these commands,hit enter:
tazhw detect-pci
lsmod

If the output from those commands don't show kernel modules loaded that begin with snd-
then the pciid of your audio chipset is not in the modules.pcimap database.
This prevents any sound modules from auto-loading.but doesn't rule out the possibility that one of the modules will work with your audio chipset.
I have to search the linux kernel driver database with the pciids of your audio chipset.
Run this command and post the complete output in your reply:
lspci -nn | grep -i audio

Hello and thanks for the quick reply!

I checked to see that linux-sound, alsa-lib and alsa-utils were installed and they were. (Versions 2.6.37, 1.0.24.1 and 1.0.24.2 respectively.) I then entered the commands you suggested and got a load of text that I couldn't fully understand, but a couple of the lines did include snd. They are presented below:

Module in use: snd_hda_intel

snd_hda_codec_realtek 202176 1
snd_hda_intel 15886 1
snd_hda_codec 45027 2 snd_hda_codec_realtek,snd_hda_intel
snd_hwdep 3808 1 snd_hda_codec
snd_pcm 43737 2 snd_hda_intel,snd_hda_codec
snd_timer 12515 1 snd_pcm
snd 33394 8 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_timer
soundcore 3357 1 snd
snd_page_alloc 4853 2 snd_hda_intel,snd_pcm

Finally, as per request, here is the full output from lspci -nn | grep -i audio:
root@slitaz:/home/tux# lspci -nn | grep -i audio
00:1b.0 Audio device [0403]: Intel Corporation 82801H (ICH8 Family) HD Audio Controller [8086:284b] (rev 04)

Open alsamixer unmute (M key) and raise Master PCM and Front levels.
Sound should work, sound and codec modules are loaded.

From what I can tell, nothing is muted. I took a screenshot of alsamixer just in case though! http://i731.photobucket.com/albums/ww316/Slugbreath/Linux/alsamixer.jpg

Get a wav sound file.
Open terminal
aplay -D default:CARD=Intel sound.wav

Any sound or error messages?

I downloaded a wav file and tried to play it.

tux@slitaz:~/Desktop$ aplay -D default:CARD=Intel 11k16bitpcm.wav
Playing WAVE '11k16bitpcm.wav' : Signed 16 bit Little Endian, Rate 11025 Hz, Mono

I couldn't hear any sound and but no error message showed up.

However, I plugged in my headset and loaded some YouTube clips that I knew had very high volume (http://www.youtube.com/watch?v=Rj3qB647poc for instance. Warning: VERY high volume in that clip) and could actually hear -some- noice if I listened very closely. This means that I theoretically can hear sounds, at least via my headset but only very, very vaguely and only when the output noice is set to max and the clips's volume is very loud.
