After emerge -avD world,
I lost the microphone.
It is not broken. I can still hear it on the head-set, if I turn it on using alsamixer.
But cat /dev/dsp gives nothing.

Somehow I seem to have lost the connection from the mircophone to
the device /dev/dsp.
Perhaps I changed a configuration file using etc-update,
but I cannot remember it.

I use ALSA as modules with ENABLE_OSS_EMUL="yes",
but all modules seem to be loaded correctly.

Can anyone help me with an idea what might be wrong?

Code:

/etc/init.d/alsasound start

 * Loading ALSA modules ...
 *   Loading: snd-card-0 ...                                                                                      [ ok ]
 *   Loading: snd-seq-oss ...                                                                                     [ ok ]
 *   Loading: snd-pcm-oss ...                                                                                     [ ok ]
 * Restoring Mixer Levels ...                                                                                     [ ok ]



Code:

lsmod

You should write what the problem really was and post a solution when marking problem with [solved].

Cheers!

Sorry about it, I just forgot to post the reply.

It was just a really stupid mistake.
I forgot to use
alsamixer,
press f4,
and turn on capture

That was the detail I was missing.
After that everything works fine.
