ALSA drivers (general question)

[soccercisco]

hi,

I am having trouble maintaining my sound configuration with the ALSA drivers (on Etch):

every time I boot I need to do the following:
zabala@terra:/usr/share/alsa-base$ sudo ./snddevices
zabala@terra:/usr/share/alsa-base$ sudo alsaconfig
zabala@terra:/usr/share/alsa-base$ alsamixer

Or else my sound card won't work. Though, I get perfect sound after these commands; I just do not want to do this everytime I boot onto the system.

I tried adding the virtual links to the rcX.d directories for my runlevels, but that didn't work.

Info:

Card: Audigy 2 ZS [SB0350]
Chip: SigmaTel STAC9721,23

hi i saw it on an another topic
try
alsactl store

[soccercisco]

thx 4 the help!

actually alsactl store (and restore) deals with the alsamixer configuration and not with the modules.

Ok, so I am on my way to figuring this out. I began to see what the heck is going on, and here is what I have found:

1. after the system booted I had no sound, so I went to the '/dev' directory and found that the '/dev/snd' directory didn't exist.

2. so I 'cd' into '/usr/share/alsa-base/' and executed './snddevices' which is a long script to post, but this is the output:

Creating mixer?...done.
Creating sequencer...done.
Creating midi0?...done.
Creating dsp?...done.
Creating audio?...done.
Creating sndstat...done.
Creating music...done.
Creating dmmidi?...done.
Creating dmfm?...done.
Creating amixer?...done.
Creating adsp?...done.
Creating amidi?...done.
Creating admmidi?...done.
Creating snd/control?...done.
Creating snd/seq...done.
Creating snd/timer...done.
Creating snd/hw??...done.
Creating snd/midi??...done.
Creating snd/pcm??p...done.
Creating snd/pcm??c...done.
Creating aload?...done.
Creating aloadSEQ...done.

3. then I went back to '/dev' and what do you know, there automagically lies the '/dev/snd' directory

4. the content at all times (that is, before and after the execution of snddevices) of 'ls -1a /lib/udev' is:

.
..
alsa-utils
check_driver

in alsa-utils I find the script:

#!/bin/sh -e
#
# udev script for alsa-utils

(
        . /lib/udev/hotplug.functions
        wait_for_file /usr/sbin/alsactl
        DEV_BASENAME="${DEVNAME##*/}"
        N="${DEV_BASENAME#controlC}"
        exec /etc/init.d/alsa-utils start $N
) &

So with this new info, can somebody tell me why my /dev/snd dissapears everytime I boot.

Thank you in advance.

Cool... Problem solved.

1. So I decided to check if udev had been updated and did an apt-get install udev

2. I turned out that this operation had to remove hotplug to install udev, so I selected 'Y'.

3. It then instructed me to purge the removal of hotplug since it had found a folder in init.d

4. Since I wasn't able to purge something that already had been removed by (2.) I apt-get install hotplug (which removed udev) and immediately did an apt-get remove --purge hotplug

5. Finally I did apt-get install udev and this time around it didn't say anything about the hotplug folder.

6. So I tried the procedure described earlier (./snddevices.... etcetera) and rebooted the system... voila... I got Sound @ boot!

Thanks to all 4 the help!
