[Ltib] cannot play sound in EA3250

[casper iway]

hello guyz, 

i was having a problem with audio of my embedded artists lpc3250 board.. I can't get it to play a sound. I was following the instruction for "Audio playback/record using ALSA on the LPC32x0" in www.lpclinux.com but to no avail. When i try to use "aplay <path>/name.wav" i got this error:
    ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
    ALSA lib conf.c:
    3513:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

    ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings

    ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory
    ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name
    ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
    ALSA lib conf.c:3985:(snd_config_expand) Evaluate error: No such file or directory
    ALSA lib pcm.c:2202:(snd_pcm_open_noupdate) Unknown PCM default
    aplay: main:552: audio open error: No such file or directory

I was wondering when i typed "cat /proc/asound/devices" i only got these two items:
  2:        : timer
  3:        : sequencer

when it should have something like "digital audio playback", "digital audio capture" and "control" as shown in the guide.

Someone know what could be my mistake? What packages to include? kernel configuration or something?

regards,

Casper
