PostPosted: Fri May 31, 2002 2:17 am    Post subject: Alsa sound problems... Reply with quote

I am on a sony vaio and using the via82cxxx_audio driver for my sound card. I have followed the instructions in the Desktop guide exactly.

My problem is that when I type amixer, I get the following error:

root@mymachnine chris # amixer
amixer: Mixer attach default error: No such file or directory

Any suggestions?

Thanks,
Chris

Ok, I got the sound working now by changing the owner and permissions of /dev/dsp. But I still get the same error when I try to run amixer and kmix just comes up blank with nothing to adjust...

Alsa has all been changed around again. The desktop guide is not accurate for that section. Does somebody here have some good (and simple) instructions for getting ALSA running from scratch :?:

have you done:
Code:
ALSA_CARDS=<your card> emerge alsa-driver
emerge alsa-oss
emerge alsa-utils

well I gues you did that.

add alsasound to the init startup scripts.
Code:
rc-update add alsasound boot

mmmm, you also did this I gues.

I added the lines to /etc/modules.autoload:
Quote:
snd-pcm-oss
snd-mixer-oss

these take care of /dev/dsp and /dev/mixer

A normal user should be added to the "Audio" group. I just hack the /etc/group file but you can use usermod with the -G option but then you have to give all groups at once. (whell/video/audio/users etc)

Well it's short but I hope it helps, Cya Alex[/code]

Kernel configuration: You don't need any sound modules, but keep SOUND SUPPORT as a module [M] (soundcore.o), ALSA uses it.
Remember, after each kernel recompile, you have to reinstall alsa-driver, because "make modules_install" removes your old modules.

This is how I did it:

Code:

# rmmod (remove all other non-alsa sound modules that might be loaded)
# emerge alsa-driver
# depmod -a
# nano -w /etc/modules.d/alsa (adjust these correctly -- see desktop howto)
# update-modules
# nano -w /etc/devfsd.conf (adjust these aswell IF needed)
# emerge alsa-utils
# /etc/init.d/alsasound start
# insmod snd-pcm-oss
# insmod snd-mixer-oss
# amixer
# amixer set Master 100 unmute
# amixer set PCM 100 unmute
# alsamixer (you can easily adjust sound with this, it's ncurse-based)
# rc-update add alsasound boot
# reboot (to see if ALSA gets loaded properly)


That's it. Good luck! :wink:
Credit goes to Sunflare, I had exactly the same problems as you configuring ALSA and he helped me out.

EDIT: made it kinda up-to-date

yep forgot about depmod -a <-> update-modules, but this is all in the normal guide. btw. I don't have /etc/init.d/alsa, had it once, but don't have it now, ain't it from an old install.????

Well if they still don't get it, :wink:

After screwing around for 2 hrs (including lots of searches here) your primer had everything fixed in 10 minutes. Thanks.

This should go into the FAQ, or even the install guide.

Thanks to you, and to Sunflare!

I am having the same problem. Followed all the instructions. No errors until I do the amixer part No Such Device.

the mod im using is snd-ac97-codec.

Sound is enabled in the kernal but no modules selected.

Could I have the wrong mod? My PC is a compac p400 deskpro and im not 100% sure thats the card.

BTW I have /dev/dsp but no /dev/mixer or /dev/dsp/mixer

-r0xxx
Sitting in silence :(
