8148音频接口

   版主好!

     dm8148中,打开"plughw:0,0","plughw:0,1","plughw:0,2;与实际对应的0、1、2通道的对应关系?

  • 你好,

    2是hdmi的音频。

      /* Name of the PCM device, like plughw:0,0 */
      /* The first number is the number of the soundcard, the second number is the number of the device.  HDMI codec is detected as 2nd device*/

      static char *device = "plughw:0,1"; /* playback device */

  •  你好:

            那你的意思是“plughw:0,0”是打开0、1、2、3等所有的通道吗?

    通道是所有的一起打开,不能一个一个打开?不知道我的理解对不对?

                     谢谢!
