板子启动后，提示一个alasctl错误
开机后提示如下错误：alsactl: parse:1655: Unable to open file '/data0/imx6_linux/alsa/tmp/share/alsa/init/00main': No such file or directory
alsactl: set_control:1267: failed to obtain info for control #55 (No such file or directory)
请问是哪里的问题？
您好，登录系统前显示的错误吗，你能把报错位置的前后打印信息的截图发一下吗 本帖最后由 小菜 于 2019-8-20 12:47 编辑
