先安装： kmod-input-core
kmod-sound-core
kmod-usb-audio
查询声卡是否有：

说明成功挂载：
再安装播放器madplay
opkg install libmad
opkg install libid3tag
opkg install madplay
3:要安装mpd

测试可以播放音乐了，可是手机端无法连接，用这个命令时出现没有库文件啥意思了？
root@OpenWrt:/usr/bin# /usr/bin/mpd --create-db
/usr/bin/mpd: can*t load library *libnsl.so.0*

U盘已经挂载
