Blaasvis · 2004-02-11 17:55:22

i written this howto for alsa:

http://www.soulfly.nl/~arjan/archlinux/alsa-setup.html

please give me feedback so i can improve it.
The reason is that i got tired of explaining alsa over and over again on irc

now i just can give them an link

Just what I need... you'll save me a lot of time. Now I don't have to figure out how to do it myself, nor do I have to document my experience.

I'll let you know when I install alsa whether or not I have any additions or changes to suggest. That was supposed to be this week...

Add users to the group:
- edit the /etc/group and add at the end of the line of "sound:x:" the name of the user you wish to give access to the soundcard.

Afaik it is recommended not to edit the file.
Instead, you will use

gpasswd -a (username) (groupname)

to add users to a group.

Nice howto. I will try it if I set up my arch on xfs, what is a bit of work.

I have a little problem:

I have a VideoLogic Sonicfury soundcard and there exists an Alsa documentation for my soundcard.

No, I followed the Alsa Howto in this thread and installed with pacman -S all packages (alsa-driver, alsa-lib, alsa-oss and alsa-utils).
The next step would be to load the modules with "modprobe <module name>".

I tried to load severals modules, e.g.
modprobe snd-sc46xxx and
modprobe snd-pcm-oss

but both commands resulted in a

modprobe: Can't locate module <e.g. snd-sc46xx>

Could someone tell me which modules to load?
@ Blaasvis: I would have asked you via E-Mail, but there is no e-mail adress in your howto.

Xentac · 2004-02-17 15:40:50

depmod -a. I guess that is a missing step in the howto. After installing alsa-driver you have to depmod -a.

Ah... and I thought it´s a kind of leet speak or how they call it

keeper · 2004-02-21 04:51:30

Well, I have followed your howto and dmeg still tells me Alsa devices found: no soundcards found.
I am using kernel 2.6.2 and I followed all the steps but no luck.
When I try to invoke amixer> amixer: Mixer attach default error: no such device
aplay: main:502: audio open error: No such device

Any suggestions will be greatly appreciated. I know I must be doing or not doing some little thing
and probably that's why I can't get alsa to work.

Regards,
Mike

Blaasvis · 2004-02-21 07:58:55

eh what soundcard ? and what modules ?

keeper · 2004-02-21 15:39:20

Sorry for not being more specific. I have a SB Live which uses the emu10k1 module. I also load snd_pcm_oss. I tried to load the snd_seq_oss modules but there is a conflict when I try to do this. Are the snd_seq_oss modules needed for alsa to work. Why isn't the card being recognized at boot time?
I'm not in Linux atm (my apologies :-)) When I am I will recheck everything I've done and do it again. If anything new comes up, I'll post the info.
Thanks a lot for your reply. I tried to get the sound working without using Alsa and wasn't able to do that either. Obviously, I'm not doing something correctly.

Regards,
Mike

I followed your tutor with one exception :
After reboot alsa loses it`s settings so after the amixer commands I did an alsactl store & added a /usr/sbin/alsactl restore in rc.local .And worked fine.

Thanks, i have had the same problem, and doing it, it is solvent and work perfectly

Thanks Blaasvis too. I was getting crazy trying alsa to work. And i think you must add the comment of SCOvsfreedom in your how-to.

PD: sorry about my poor english, i'm spanish

keeper · 2004-02-21 16:42:05

Ok. here is the output of lsmod: snd_pcm_oss, snd_pcm snc_page_alloc snd_mixer_oss
ac97_codec(emu10k1) sound(emu10k1

Alsa will not recogozie my SBLive card, therefore I can't access alsactl ,etc. I have placed alsamixer in the daemons array, but it also throws an error and will not load. At this point, I haven't a clue. Help!!! :-)

keeper · 2004-02-21 16:56:46

Well, I know that my sound module is loaded. Lsmod tells me so, but when I do dmesg | grep sound it says that no soundcards found. Could this be a glitch in the 2.6.2 kernel?(probably not, but I had to ask)

Regards,
Mike :-(

luisfeser · 2004-02-21 18:28:21

hello keeper,
This is my lsmod about sound:
snd_pcm_oss,snd_mixer_oss,snd_emu10k1,snd_rawmi di,snd_pcm,snd_timer,snd_seq_device,snd_ac97_codec,snd_util_mem,snd_hwdep

I have a SB live like you. When i compile my kernel (6.2.3) i include alsa as a module and i don't include oss (but yes the alsa oss emulation)

Are you sure you modprobe de correct module?
- emu10k1 is the oss module
- snd_emu10k1 is the alsa module

good luck

I got follwing problem:

I compiled my Kernel 2.4.25 myself, because my DSL-Modemdrivers need special Kernel settings. After installing alsa-pakages with pacman i make a "depmod -a" but there seem to be several Problems with alsa:

I use a Terratec DMX XFire1024 which uses snd-cs46xx as ALSA driver, but of course a "modprobe snd-cs46xx" fails :

[root@myhost /]# modprobe snd-cs46xx
/lib/modules/2.4.25/kernel/sound/acore/snd-page-alloc.o: /lib/modules/2.4.25/kernel/sound/acore/snd-page-alloc.o: unresolved symbol vmalloc_to_page_Rsmp_4e3c2c2f

/lib/modules/2.4.25/kernel/sound/acore/snd-page-alloc.o: insmod snd-cs46xx failed

What is wrong? Should i disable Kernel sound support completely?

EDIT: OH! Sorry :oops: ! Just saw in the forum, that alsa-driver-pakages are compiled for ArchLinux-standard-kernel. I didn't know about abs, but now i'm compileing a pkg of alsa-driver for my costum-Kernel 2.4.25 at the moment !

OK "depmod -a" now keeps silent ! No errors, but now i have a new problem :

[root@myhost alsa-driver]# modprobe snd-cs46xx
/lib/modules/2.4.25/kernel/sound/pci/cs46xx/snd-cs46xx.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.25/kernel/sound/pci/cs46xx/snd-cs46xx.o: insmod /lib/modules/2.4.25/kernel/sound/pci/cs46xx/snd-cs46xx.o failed
/lib/modules/2.4.25/kernel/sound/pci/cs46xx/snd-cs46xx.o: insmod snd-cs46xx failed

What's wrong? Please help a ALSA-noob :?. (SuSE 8.2 handled sound-configuration with Yast2 so far :twisted: !)

Have you tried modprobe soundcore......?

Hmm....

modprobe soundcore

Mr Green · 2004-03-06 17:25:13

Are you sure drivers are there......

lib/modules/2.4.25/kernel/sound/pci/

Have you looked ?

Have you got all the alsa libs installed.....

ActionNews · 2004-03-06 18:11:02

I recompiled and installed alsa-driver, alsa-lib, alsa-utils and alsa-oss so they should match with my Kernel 2.4.25.
/lib/modules/2.4.25/kernel/sound/pci/cs46xx/snd-cs46xx.o exists too.

Perhaps this is interesting too:
dmesg says: "Sound Fusion CS46xx soundcard not found or device busy".

I activated Soundcard support when i compiled the Kernel, but didn't choose any driver. Perhaps it's a configuration error of the Kernel :?:

ActionNews · 2004-03-07 07:34:53

Hmm... this is strange: After a reboot there is no /dev/dsp or /dev/mixer anymore :shock:! This seems to be the failure? But how can i solve it?
