trying to load sound module

Although I've been using Debian for over ten years, I don't consider myself a guru, so I'm hoping that some real gurus will jump in here and help me out. ;)

I'm running wheezy with the 3.0.0.1 kernel on a P4 3.0GHz machine, and I'm wanting to install a sound card called an Echo Layla 24 (a card/interface used for multi-track recording). The module is snd-layla24 which is in the kernel, but I'm having a heck of a time getting this to work. The card is a few years old and most of the online documentation is old as well, including the installation docs at alsa-project.org. Here's what I have so far:

Code:

Revolver:/home/rl5# lspci

02:09.0 Multimedia controller: Motorola DSP56361 Digital Signal Processor (rev 01)

Linux sees the card. Now lsmod:

Quote:

Revolver:/home/rl5n# lsmod

usb_storage 35269 0
soundcore 12992 1 snd
uas 13178 0
snd_page_alloc 12899 2 snd_layla24,snd_pcm

The module shows up with lsmod but:

Code:

Revolver:/home/rl5# modprobe s <tab>

samples/    soundfonts/ sysv-rc

It doesn't show up here.

And when I try aplay:

Code:

Revolver:/home/rl5# aplay -l 

aplay: device_list:242: no soundcards found...

There is a mixer for this card - echomixer - which I have installed, but the mixer will not start.

I added the module to /etc/modules like so:

Code:

/etc/modules

ide-cd

ide-disk

ide-generic

psmouse

snd-layla24

snd-seq

But no luck.

SO can anyone tell me why this module is not loading, and what I can do to fix it? I would be greatly appreciative! :)

hi

I am not an expert....being Debian the thing that crossed my mind is firmware.

2) can you post this section of your /boot/config-kernelversion pls as that might suggest .....you have no firmware loader support in your current kernel...or firmware is being prevented in being built....for a newer firmware you can install from alsa-project.org

-------------
# Device Drivers
#

#
# Generic Driver Options
#
CONFIG_UEVENT_HELPER_PATH=""
CONFIG_DEVTMPFS=y
# CONFIG_DEVTMPFS_MOUNT is not set
CONFIG_STANDALONE=y
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_FW_LOADER=y
# CONFIG_FIRMWARE_IN_KERNEL is not set
CONFIG_EXTRA_FIRMWARE=""

3) I have read your alsa-project link....but you have not reported ALL steps you attempted for their doc
It is clear aplay -l is not good

4) In the meantime....getting info out of log is good

Can I suggest you first add your module with root powers to the blacklist at
/etc/modprobe.d/alsa-base-blacklist.conf with entry like so

blacklist snd-layla24

Note we use hyphen and not understem

reboot and run lsmod...mod must not load

now with root powers run

modprobe snd-layla24
lsmod

if it loads now post the section of /var/log/messages relevant to our loading pls

good luck

oh I have trouble with my browser so forgive lack of edit

before you try above stuff download this file

http://www.alsa-project.org/alsa-info.sh

as a local user run

Code:

chmod +x utils_alsa-info.sh

YES it changes its name!!

now run it as a local user...keep it local stored

then post to

http://ompldr.org/ (no expiry) or http://paste.debian.net/ and choose 72 hours or never (your choice)

I am particularly interested in whats in your asoundrc or module.conf type file for the alsamixer issue as well as the other juicy stuff.

b) then run the blacklist / modprobe stuff with log output.
as that log is smallish...post here

I forgot to mention before blacklisting run

lsmod > /home/(yourname)/lsmod1

then blacklist etc

lsmod > /home/(yourname)/lsmod2

are they the same?....xxdiff will tell you ....

Code:

xxdiff lsmod1 lsmod2

I added snd-layla24 to alsa-base-blacklist.conf, but it still shows up with lsmod:

This is with the mod blacklisted:

Code:

Oct 25 00:16:23 Revolver kernel: [    9.283264] Echoaudio Layla24 0000:02:09.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21

Oct 25 00:16:23 Revolver kernel: [    9.308797] Echoaudio Layla24 0000:02:09.0: PCI INT A disabled

Oct 25 00:16:23 Revolver kernel: [    9.308853] Echoaudio Layla24: probe of 0000:02:09.0 failed with error -2

This is with the mod removed from the blacklist:

Code:

Oct 25 00:36:52 Revolver kernel: [    6.773740] Echoaudio Layla24 0000:02:09.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21

ok there are few things we need to get out of the way lets go for the main one....your hardware listing.

the alsa.sh file confirms you do not have a config in any module conf file or asoundrc etc (I was not actually asking for you to do extra but I do appreciate your enthusiasm.

I will look at why your blacklist failed later ok

2) I do not use firmware and do not have (below) folder ....I use a Debian sid so do not have
/lib/alsa/modprobe-post-install

AND there is bug for those distros still using it and using udev.....they conflict as per
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=518242

Quote:

Support for the modprobe-post-install scripts should be removed because
it duplicates the functionality of the udev scripts, at a cost.

Popularity contest shows that with good approximation udev is installed
on every modern debian systems (presence of modutils denotes a pre-lenny
and probably pre-etch system)

my versions are.............................yours are the same
Driver version: 1.0.24
Library version: 1.0.24.1
Utilities version: 1.0.24.2

ok first try turning off that post script

Code:

sudo su

(or su to get root powers)

find / -name modprobe-post-install

chmod -x /pathway2/modprobe-post-install

(pathway) likely to be /usb/bin

INTENTION
We need to stop that alsa post install script first

Now reboot and check

aplay -l

udev should give you the correct hardware settings but if not we may have to create an asoundrc....you already know how to do this....your link to alsa-project page.

good luck

aus9	10-25-2011 07:19 AM

ok that last bit might be considered rude eh?

so a little secret ...I don't use any asoundrc or modprobe.conf

just edit with root powers your
/etc/modprobe.d/alsa-base.conf

YMMV

mine reads

http://ompldr.org/vYXowZA/alsa-base.conf

yours will read....if needed...if the disabling of your post install fails

http://ompldr.org/vYXowZw/layla

but you use root powers to edit those last lines.

as a backup and assuming you have a live cd and know how to get back to the net....post your current alsa-base.conf file here before rebooting and keep a local copy somewhere like /home/yourname

so what we are trying to do is eliminate extra scripts interfering with our normal alsa stuff
if that works run the alsa.sh script to check its contents

if if fails then use root powers to edit your alsa-base.conf to include more hardware stuff for Alsa to get its teeth into

good luck

rl5	10-26-2011 05:34 PM

I appreciate all of your help... I only wish I had some good news to report. :(

Code:

find / -name modprobe-post-install

This command doesn't return anything, so I moved on to this:

I backed-up my alsa-base.conf and used this one, then rebooted. No change.

Code:

Revolver:/home# aplay -l

aplay: device_list:242: no soundcards found...

http://ompldr.org/vYXp1eg/alsa-info.txt.DOn6eChMum

It's still not finding the lalya module... I'm tempted to purge all alsa apps and start over! :scratch:

aus9	10-26-2011 06:27 PM

ok well thats weird you can't find it going back to your link
http://ompldr.org/vYXl2YQ/modules.conf

its mentioned eg.....post-install snd-layla24 /lib/alsa/modprobe-post-install snd-layla24

so go to file manager and peek into that lib folder pls

run file against it to see if its executable or run

Code:

/lib/alsa/modprobe-post-install

2) IF not found .... install the package called packagesearch pls

run it.....

after it loads click on the pulldown and choose "installed"
then run search string "alsa"
in the results
click on each alsa and right tab for Files......this should reveal where that pesky post-install stuff is

3) you could remove your debian packages and install the alsa projects's

to eliminate other sound devices pls list any connected devices that use sound at time of boot up pls
eg
mobile phones
modems
mp3 players
usb sound mixers
etc

ahhh my browser

forget that code box its missing ls -al

try

Code:

ls -al /lib/alsa/modprobe-post-install

aus9	10-26-2011 06:31 PM

oops I forgot to mention you need root powers to run that find command

I do not have a /lib/alsa directory. :scratch:

Not sure why post-install shows up in modules.conf - I just checked again and it is still listed there.

Quote:

Nice app, but I've search through all of the packages that were returned in the search and I cannot find modprobe-post-install.

BTW, I have been keeping up with recent updates from Debian - could a recent update have removed it?

Quote:

Well, I might be ready to try this.

Quote:

AFAIK there are no other sound devices attached - and the layla card is the only sound card attached.

aus9	10-28-2011 12:32 AM

yeah well I am not sure why the alsa.sh stuff link is reporting that post alsa stuff.

2) err also I lied to on my own config.

I use /etc/modprobe.d/alsa-base.conf but the correct info should read

# my configs
options snd-hda-intel model=5stack

your card will differ.

3) OK I run sid packages.

if interested and forgive me if you don't want to try it....consider removing your current packages and installing "sid" packages.

However, I run a pure sid so in pulling in sid to a stable system it might break?
Therefore can I suggest you place copies of the files you are going to change on removable media and know how to boot into single or use a live cd pls

Here is ONE howto do it.
http://wiki.debian.org/AptPreferences
/etc/apt/sources.list.d/debian.lst

deb http://ftp.iinet.net.au/debian/debian sid main contrib non-free

eek I forgot to tell you that you should try to remove...don't remove libasound2 as it removes too much IMHO

Code:

su

apt-get remove --purge alsa-base alsa-utils

apt-get update (when you comment out your current source)

apt-get install alsa-base alsa-utils

apt-get install alsa-base alsa-utils

So you think I should do this instead of installing alsa-project files?

aus9	10-28-2011 05:01 AM

no only a suggestion it is less compiling.

if you are happy to download unpack and configure using the correct parameters to enable your device feel free.

I am lazier (winks)
