[gentoo-user] yet more ALSA trouble

[gentoo-user] yet more ALSA trouble

[Phil Thomson]

Hi,

Reading the archives, I noticed there's been a looooooooong thread on
ALSA trouble, so I hesitate to post a similar problem, but following
the relevant steps outlined in that thread so far hasn't seemed to
help my own problem with ALSA.

I've been trying to get ALSA working with my Nvidia nForce2 AC97
onboard sound card, but without much luck. I've been following the
guide at http://www.gentoo.org/doc/en/alsa-guide.xml and I think I've
got all the steps done, but when I run alsaconf it goes through all
the steps till it gets to the "ALSA configurator". When I press OK
here, I get:

Running modules-update...
Loading driver...
 * Loading ALSA modules ...
 *   Loading: snd-card-0 ...                                              [ ok ]
 *   Loading: snd-pcm-oss ...                                             [ ok ]
 *   Loading: snd-seq ...                                                 [ ok ]
 * ERROR: Failed to load necessary drivers                                [ ok ]

Setting default volumes...
Saving the mixer setup used for this in /etc/asound.state.
/usr/sbin/alsactl: save_state:1163: No soundcards found...

and then:

 Now ALSA is ready to use.
 For adjustment of volumes, use your favorite mixer.

 Have a lot of fun!

and then no sound. If I open, for example, xmms and try to get it to
use alsa output, I get an error message. It's not that the sound is
muted; it says "Failed to open audio output: ALSA 1.2.10 output
plugin".

Here's some info about my system:

/proc/asound/cards has nothing in it.

I've tried my best to resolve this on my own, including Googling,
posting on the Gentoo forums, and reading the long thread about ALSA
which recently closed, but I'm still a bit of a newbie to Linux, so I
may be missing something obvious. Thanks in advance for any help or
advice.

I cannot really help you, but maybe searching the archives of ALSA-user 
or linux-audio-user will give you some hints.


Best regards

I have a nForce2 board as well, here is what I have.

Not sure that helps or not, but it looks like there are a few things
missing from your config. Specifically this section:
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore

Hope that helps,

I have a Abit NF7 mobo with on board sound and it was sucky.  There was
no mixer support so only one sound at a time.  I went to newegg and got
me a soundblaster card and it is a LOT better.  You may not can but I
thought it worth mentioning so you will not be to disappointed with it.

Now I wish I had saved that old drive with Mandrake on it.  I could post
what I had in my config files.  It did work, just not near as good as
Soundblaster.
