[CLAM] sound capture

[Ismael]

Greetings.
I have a problem with sound capture through microphone using the AudioIn
class, AudioManager, etc... under linux
The following error appears in running time:

pcm.c:920: snd_pcm_prepare: La declaración `pcm' no se cumple.
Abortado

file path pcm.c:

/usr/src/linux-2.4.20.SuSE/sound/core/pcm.c

The program works well under windows and artsd is killed

linux distribution: SuSE 8.2
sound card: SB Audigy
sound devices:

ls -l /dev/snd

If somebody knows the nature of the problem and can help me I should be very
grateful.
Thanks.
