alsamixer issues?

alsamixer issues?

[Chris Wenn]

Can anyone give me a hand with the following problem?

I installed a new 2.4.18 kernel image today, upgrading from my 2.4.17 
image. After I installed this, alsa broke, refusing to load at 
boot-time, claiming that the alsa driver could not be found. This 
required a full re-compile and install of alsa.

I have compiled and installed the alsa 0.9.0beta12 drivers, libraries 
and utilities as instructed in the INSTALL files for each package 
(including ./snddevices) but cannot get alsamixer to run. Whenever I 
invoke it, I get the following error

#alsamixer: function_snd_ctl_open failed for default: No such file or
	directory

amixer gives the following, slightly different message

#amixer: Mixer attach default error: No such file or directory

This isn't a permissions problem, as the same happens when I am logged 
in as root. The alsa drivers for my sound card (snd-card-es1968 - 
Terratec SoundSystem DMX) are loaded on bootup, so they're not lost in 
the mess. What the sam hell is going on?

I think that anytime you change kernels alsa needs to be recompiled
because it has to be able to resolve the symbols of the currently
running kernel.

This sounds like the driver has not been loaded...

looks like the same problem.

shouldn't snd-card-es1968 be snd-es1968 now? What version of alsa were
you using before? how are you loading the drivers at boot-up

You need to re-'./configure && make && make install' the 'alsa-drivers'
package. The other packages do NOT need to be recompiled, and once
you've built the drivers for all of your installed kernels, you can
switch between them freely.
