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!
