trying to enable the sound in Debian Lenny


Hi, I'm using Debian Lenny, the only problem that I have is that the sound card isn't recognize by the system, I have installed ALSA 1.0.20 and I followed several tutorials trying to enable my sound card (ATI tech Azalia (Intel HDA)but all tries fail.

So, after install another distro in the same pc I figured out that the sound card is enable and running by default, the ALSA version is the same -1.0.20- but the kernel is different -2.6.31.xx- so my questions are:

1. do you recommend me to upgrade my lenny's kernel to fix the problem?

2. is there a way to upgrade specific packages -for example samba, alsa, kernel- using unstable or testing versions instead of upgrade the entire distro? actually I'm confortable with lenny

3. what configuration should I check in the "other" distro to use that parameters in lenny?

thanks, all the best

You can upgrade to the kernel from backports.

instructions [Debian Backports] - http://www.backports.org/dokuwiki/do...d=instructions

Google the sound card using the output of lspci -nn

alsa-checklist
1) add yourself to the 'audio' group (log out and log in again) 2) use alsamixer and unmute channels and raise levels (also try muting some channels & toggle jack sense) 3) arts or esound stopped? 4) OSS modules unloaded? 5) speakers on? 6) modprobe snd-pcm-oss 7) does
"aplay /usr/share/sounds/alsa/Noise.wav" work for root? Test your sound with aplay and a wav so codec issues don't confuse the situation.


To see what processes are using (and perhaps blocking) your sound device:
Code:
ps `lsof +D /dev -F rt | awk '/^p/ {pid=$1} /^t/ {type=$1}  /^r0x74..$/ && type == "tCHR" {print pid} /^r0xe..$/ && type == "tCHR" {print pid}' | cut -c 2- | uniq`
. Alternatively,
Code:
fuser -v /dev/snd/*  /dev/dsp /dev/mixer
You can check the output of lsmod in the distro that has working sound to see what modules are loaded.
