| Abstract: | Advanced Linux Sound Architecture （ALSA） audio system framework has become the mainstream audio system framework. According to the specific hardware platform, ALSA driver of the audio codec TLV320AIC3110 was roughly described. Meanwhile, Dynamic Audio Power Management（DAPM） widget and the configuration of audio path in the driver was introduced in detail. At last, the test results show that the driver can run stably. |
