ti 8168 dvrrdk 的音频设备打开失败

Other Parts Discussed in Thread: TVP5158

你好:

我最近在调试音频,dm8168 dvrrdk, 只使用tvp5158,

但是一打开音频设备就失败,snd_pcm_open失败

打印如下:

ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card
AUDIO >>  cannot open audio device plughw:1,0 (No such file or directory)

是不是音频设备需要手动挂载,

 /dev 下也没有看到plughw:1,0,

请教达人?
