-- Modules section
:
There is one section per audio HW module present on the
platform.
Each module section will contains two mandatory tags for audio HAL “halVersion” and “name”
.
The module names are the same as in current
.conf file
:
“primary”, “A2DP”, “remote_submix”, “USB”
Each module will contain the following sections
:
“devicePorts”
: a list of device descr
iptors for all input and output devices accessible via this
module
.
This contains both permanently attached devices and removable devices
.
“mixPorts”
: listing all output and input streams exposed by the audio HAL
“
routes”
: list of possible connections between input and output devices or between stream and
devices
.
"
route"
: is defined by an attribute
:
-"type"
: <mux|mix> means all sources are mutual exclusive
(mux) or can be mixed
(mix)
-"sink"
: the sink involved in this
route
-"sources"
: all the sources than can be connected to the sink via vis
route
“attachedDevices”
: permanently attached devices
.
The attachedDevices section is a list of devices names
. The names correspond to device names
defined in <devicePorts> section
.
“defaultOutputDevice”
: device to be used by default when no policy rule applies

3 Coloros15，安卓版本15，修改该文件，绕过安卓音频SRC实现系统全局自适应采样率（Dynamic sampling rates）、自适应位深（Bit_perfect）（保持音频文件原始位深，16bit文件不升级位深）、禁用升频和重采样，关闭所有音频音效（effect）以及影响音频质量无损输出的一切音频处理，最大程度上抑制并降低音频抖动（jitter）
(最大化优化时钟管理和同步)、最大程度降低音频失真和噪声以及电源纹波和噪声，以输出输入最干净无污染最高质量的HIFI无损原始音频信号直出，输出修改过的完整文件
本文介绍了一种KVM虚拟机中遇到的网卡启动错误问题及其解决方法。通过对日志的分析，发现问题是由于NetworkManager服务引起，并通过停止该服务成功解决了问题。
