I have the same error.
I posted at http://forums.gentoo.org/viewtopic.php?t=121194.

I didn't edit my /etc/modules.d/alsa what do you need to change there?

I've followed the guide(s) from this post, and I've gotten ALSA to load with all the modules and other bits, but I keep getting an error from alsacrtl stating that "no soundcards found...", and I get similar errors from alsamixer, and amixer. What am I doing wrong?

You have to specify your soundcard there. e.g. mine reads:
Code:
# Alsa 0.9.X kernel modules' configuration file.
# $Header: /home/cvsroot/gentoo-x86/media-sound/alsa-utils/files/alsa-modules.conf-rc,v 1.1 2003/08/05 21:07:55 johnm Exp $

# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore

##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
##  ALSA portion
alias snd-card-0 snd-emu10k1
alias snd-card-1 snd-intel8x0
##  OSS/Free portion
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
##

# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
##  OSS/Free portion - card #2
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.

Did you do
Code:
nano -w /etc/modules.d/alsa
modules-update
for specification of your soundcard?

So your sound card is recognized by ALSA (it will show at boot-up)? If all is well then I can only think of hardware-related problems, e.g. are the cables & connections right, speakers switched on, volume up etc.

The latest akpm patches (used by mm-sources) 2.6.1-mm1 and mm2 have the latest Alsa in them, 1.0.1, which may help some people having problems.

The 'standard' kernel 2.6.1 is pretty outdated, with v0.9.7.

IMMO, you said you unmuted the speaker etc... Does that mean you unmuted Master, PCM, CD, Headphone also? :)

Same problem here (and a lot of other places). It's all seems ok but no sound.
I have an AN7 card (Realtek ALC658 chipset) and i can't get the sound working. I've done pretty much all the combinations of modules-builts in-drivers(from ALSA, not kernel) but nothing. So i am just sitting here, expecting a revelation or some patch.
P.S: please... stop about the unmute thing... all inteligent people read Docs first (thanks)

I wasn't talking about unmuting, I meant "real" hardware problems. I myself discovered more than once that I forgot to switch on the speakers or plugged the audio cable into the wrong jacks, etc.

I will try to help, but I'm not a Linux expert. Can you post the output of dmesg?

Helena, glaskow was talking about me.

I also agree, we need some more info. Output from dmesg would be a good start. Also manually stop alsasound and then restart it post any output from it.

As for unmuting, there are about 20 -30 settings in the mixer, if immo didn't unmute the proper thing it won't work. Especially since he said he didn't get any errors. :)

Hello I have some kind of permission problem with my alsa installation.

I have compiled eveyting as modules, when I boot I get errors that tells me that my soundcard (maestro3) is already loaded into the kernel. I have seen a few other people here with the same problem. But from what I can tell that is not such a big problem.

However when I last night was sitting and fiddeling with the installation I menaged to get it all up and running. But now when I rebooted it looks like alsa starts fine but when I try to play I get this:
Code:
 aplay /usr/lib/MozillaFirebird/res/samples/test.wav
Playing WAVE '/usr/lib/MozillaFirebird/res/samples/test.wav' : Unsigned 8 bit, Rate 22050 Hz, Mono

In the /etc/devfsd.conf I have the permissions specified in the gentoo alsa guide. Namley

LOOKUP          midi         MODLOAD
REGISTER        sound/.*     PERMISSIONS root.audio 660
REGISTER        snd/.*       PERMISSIONS root.audio 660


does anyone have any ideas??

EDIT: I solved it.. It was a problem with the init script. It doesn't work att boot but it does when I start it manually. So now sound is go.

Is your normal user a member of the group audio?

Incidentally, the errors about modules already being loaded aren't critical, so maybe you should not have played around with them. These spurious error reports are fixed with the latest alsasound init script (which is in ~x86).

Eh ... no. Now I don't know if it's because you've got a 2.6.1-gentoo kernel (as opposed to Linus's 2.6.1 from kernel.org), or if what you are doing is reporting the alsasound initscript and/or alsa-lib/alsa-utils version you have installed, but when you do
Code:
cat /proc/asound/version
with kernel 2.6.1 (what you get with development-sources), I get this-
Code:
Advanced Linux Sound Architecture Driver Version 0.9.7 (Thu Sep 25 19:16:36 2003 UTC).
Compiled on Jan  9 2004 for kernel 2.6.1.
and with 2.6.1-mm2 (what you get with mm-sources), I get this-
Code:
Advanced Linux Sound Architecture Driver Version 1.0.1 (Tue Dec 30 10:04:14 2003 UTC).
Compiled on Jan 10 2004 for kernel 2.6.1-mm2

Which indicates that the ALSA driver included with the standard 2.6.1 kernel is over 3 months old, whereas the driver included with 2.6.1-mm2 is only about 3 weeks old.

Regardless, the ALSA driver with 2.6.1-mm2 is the most up-to-date.

If u still have no sound, and everything looks ok... try this:
Enable "Line-in as Sorround" and "Duplicate Front" at alsamixer, then connect your speakers to the line-in. It works for the Abit AN7 (nforce2 chipset + Realtek ALC658).

Ah! Thanks for the reminder. I vaguely remember having to do this even before with the 2.4 kernel. I have an Asus A7V8X-X MB with onbard via8233 sound controller and can only get it working by doing what glaskows said.

FYI, I compiled the ALSA settings into the kernel and am using alsa-lib/alsa-utils 1.0.1 (the latter providing the alsasound init script now)

This is what I did, after trying everything else in this thread to no avail:

1. Compile the kernel with ALSA w/ OSS Emulation into the kernel, and the driver for your soundcard as a module.

2. Reboot with your new kernel.

3. Run 'alsaconf' -- it will find your card, turn it on, and now you are good to go!

for all KDE users: changing volumes with Kmix and saving them as default restores everything fine.

I got ALSA fully compiled into my kernel, everything works. next step for me will be activating dmix.

PostPosted: Tue Jan 20, 2004 9:08 pm    Post subject: ALSA configured, kernel 2.6.1-r1, no sound Reply with quote

Hi all,

mine is another "no sound" problem. With everything perfectly configured.

with "perfectly" I mean:

  • kernel 2.6.1 with ALSA configured as modules
  • alsa-lib and alsa-utils 1.0.1
  • /etc/modules.d/alsa OK
  • alsasound in the runlevel boot
  • of course the card is UNMUTED (correctly unmuted, I'm used to ALSA)
  • of course the speakers are working (sound is working with OSS, just it doesn't with ALSA)
  • NO ERRORS displayed
  • alsaconf detects and configures my card with any problem.


note:

  • I've used ALSA since kernel 2.4.10 without problems. It was working 3 weeks ago !!!
  • I read how-tos.
  • no changes in my hardware.
  • I just upgraded my kernel and my alsa-lib & utils.
  • now kernel 2.6.1
  • intel8x0 chip


I tried to come back to kernel 2.4.x but --> NO SOUND.
I think the problem is around alsa-lib >= 0.9.8 but I can't come back to 0.9.2 because it requires alsa-driver installed ... and I can't install alsa-driver with kernel 2.6.1

what do you think ?

thanks, simone

Try mm-sources, it has the latest alsa drivers

Use ~x86 to install alsa-lib and alsa-utils, it will give you the latest versions

Don't use alsaconf - edit your /etc/modules.d/alsa by hand, and remember to run update-modules after.

Don't use alsaconf - edit your /etc/modules.d/alsa by hand, and remember to run update-modules after.


  • I'll try mm-sources

but :

  • of course I use ACCEPT_KEYWORDS="~x86"
  • of course I edit my /etc/modules.d/alsa by hand and of course I run update-modules.
  • of course I tried everything I could read on Gentoo How-To and some things more.
  • I run alsaconf just as the last resort


thanks, simone

Hi raab,

raab wrote:
Ok, basically I followed the same kernel configuration, everything as modules.

Next I emerged alsa-lib-0.9.2.ebuild, then alsa-utils-0.9.2.ebuild, ran alsamixer increased the master volume to 100, started kde and sound worked..


I have a lot of problems compiling alsa-lib-0.9.2 & alsa-utils-0.9.2 with 2.6.x kernel ....
I think because they requires the alsa-drivers & the kernel-2.4.x tree ...
any suggestion ?

tnx

I did it right now, but no sound.
the dmesg output is:

Code:

intel8x0_measure_ac97_clock: measured 49337 usecs
intel8x0: clocking to 48000
request_module: failed /sbin/modprobe -- char-major-226-0. error = 256

what about RTC support in ALSA ? I tried Y & N ...

please help ...
tnx, simone

RTC support shouldn't make a difference, and try to stay away from any alsa stuff < 0.9.7

I've only set up one Linux box using the 8x0 alsa driver and that was over a year ago. iirc there are many different implementations of this hardware, and I'm sure I've seen boot errors w.r.t. the clock/timing before as well. It could be that your particular mobo sound is not supported properly - you might be better off asking questions on the alsa-user mailing, or the linux kernel mailing list since alsa is in the kernel. There may be an alsa module parameter you can pass to it which would force the issue, but I don't know.
