为什么将sound card support选项模块化后，视频就出问题了？

我在DM368-IPNC内核配置里将sound card support选项模块化，视频就出不来了，我仔细看了下启动日志，发现有如下错误：

ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4184:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

哪位大侠懂的帮忙看看吧，小弟跪谢！
