声卡移植出现 no soundcard found

ASoC version 0.13.2
ALSA device list:
  No soundcards found.
TCP cubic registered
NET: Registered protocol family 1
RPC: Registered udp transport module.
RPC: Registered tcp transport module.
drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
yaffs: dev is 32505858 name is "mtdblock2"
yaffs: passed flags ""
yaffs: Attempting MTD mount on 31.2, "mtdblock2"
yaffs: auto selecting yaffs2

按照step by step做的，编译都没有问题，竟然出现没发现声卡，看看怎么回事

我自己试过了，没问题的，上面那里有出现那句：UDA1341 audio driver initial ized
测试也正常。只是不知道为什么下面也会同时出现No soundcards found.还请指点
