From http://www.rpsys.net/openzaurus/patches/alsa/info.htmlALSA SoC LayerThe overall project goal of the ALSA system on Chip (ASOC) layer are to provide better ALSA support for embedded System on Chip processors (e.g Pxa2xx, au1x00, IMX, etc) and portable audio codecs. Currently there is some support on the kernel for SoC audio, however it has some limitations:- Currently, codec drivers is often tightly coupled to the underlying SoC CPU. This is not a ideal and leads to code duplication

quite a few people, about 70 people. I took a place to sit down. Jimmy started talking at. There was a lot of English. It was nothing more than that of everyone who was eager to learn. The prospect of the big computer was good, or something. However, the MIC was not good, and some did not hear clearly. It seems that I still mentioned Java and didn't understand it... then, a teacher started to give a lecture. He was an old man in his 40 s. He was ta

You can call the release () method in the Initial status to enter this status, all resources bound to the MediaRecorder object will be released. Error: indicates the Error status. When an Error occurs, it enters the Initial status through the reset () method. Tip: similar to MediaPlayer, when using MediaRecorder for

Example of headset plugging and audio channel switching for Android underlying development Example of headset plugging and audio channel switching for Android underlying development Because the headset is separated by the headset microphone, the incident should be reported separately. In the Android system layer, the earphone Jack is determined based on the value of/sys/class/switch/h2w/state (in the example of 4.4.4 _ r2, WiredAccessoryManager. java ). You only need to implement a "True or f
