Hi to all,
I am working on Alsa Soc driver i wanted to interface the au1200's (i2s) to tsc2301(audio codec) and when testing the audio driver with aplay following is the error,

sh-3.2# aplay Noise.wav
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:2184: (snd_pcm_open_noupdate) Unknown PCM default
aplay: main:583: audio open error: No such file or directory

Can anyone give me the solution for the driver errors.waiting for valuable suggestions.

Thanks in advance
