# 定制 本节提供有关音频定制、软件配置、接口定制和自定义模块添加的详细信息。 ## 音频模块源代码 音频模块的源代码可用于应用程序的定制开发。 | 模块 | 源代码位置 | | --- | --- | | [PulseAudio](https://docs.qualcomm.com/doc/80-70017-16SC/topic/software.html#pulseaudio-sw) | `build-qcom-wayland/workspace/sources/pulseaudio` | | [PAL](https://docs.qualcomm.com/doc/80-70017-16SC/topic/apis_and_sample_apps.html#pal-sw) | `build-qcom-wayland/workspace/sources/qcom-pal/opensource/arpal-lx` | | [TinyALSA](https://docs.qualcomm.com/doc/80-70017-16SC/topic/apis_and_sample_apps.html#tinyalsa-sw) | `build-qcom-wayland/workspace/sources/tinyalsa` 和 `build-qcom-wayland/workspace/sources/tinycompress` | Note 其他音频模块可供对 Qualcomm Linux 附带的专有软件具有完全访问权限的开发者使用。更多信息，参见 [Qualcomm Linux Audio Guide - Addendum](https://docs.qualcomm.com/bundle/resource/topics/80-70017-16A/customize_addendum.html#source-code-of-audio-modules)。 下表显示了不同硬件版本的配置文件： QCS6490 配置文件 | 版本 | 声卡名称 | Conf 文件 | mixer\_paths.xml | ResourceManager.xml | | --- | --- | --- | --- | --- | | 核心套件 (RB3) | qcm6490-rb3-snd-card | qcm6490-rb3-snd-card.conf | mixer\_paths\_qcm6490\_rb3.xml | resourcemanager\_qcm6490\_rb3.xml | | 机器视觉套件 | qcm6490-vision-snd-card | qcm6490-vision-snd-card.conf | mixer\_paths\_qcm6490\_vision.xml | resourcemanager\_qcm6490\_vision.xml | | 视频协作套件 | qcm6490-vc-snd-card | qcm6490-vc-snd-card.conf | mixer\_paths\_qcm6490\_vc.xml | resourcemanager\_qcm6490\_vc.xml | QCS9075 配置文件 | 版本 | 声卡名称 | Conf 文件 | mixer\_paths.xml | ResourceManager.xml | | --- | --- | --- | --- | --- | | Qualcomm IQ-9100 Beta 评估套件 | qcs9100-ridesx-snd-card | qcs9100-ridesx-snd-card.conf | mixer\_paths\_qcs9100\_ridesx.xml | resourcemanager\_qcs9100\_ridesx.xml | ## 同步和编译音频组件 音频软件涉及用户空间和内核空间模块，这些模块在支持 Linux 的音频软件目录中提供。 音频用户空间和内核模块源代码树被提取到 <workspace>/build-qcom-wayland/workspace/sources path。下面介绍了使用 [devtool Linux 工具](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-27/user_customizations.html#use_of_devtool)来获取和提取音频模块源代码以及构建用户空间和内核模式模块的说明。 Note 转到工作区 (`/build-qcom-wayland$`) 以使用 devtool 访问源代码树。 ### PulseAudio 1. 执行以下命令，以提取源代码树： devtool modify pulseaudio Copy to clipboard 将 PulseAudio 源代码树提取到 `build-qcom-wayland/workspace/sources/pulseaudio`。 2. 执行以下命令，构建源代码树： devtool build pulseaudio Copy to clipboard ### PAL 1. 执行以下命令，以提取源代码树： devtool modify qcom-pal Copy to clipboard 将 PAL 源代码树提取到 `build-qcom-wayland/workspace/sources/qcom-pal/opensource/arpal-lx` 2. 执行以下命令，构建源代码树： devtool build qcom-pal Copy to clipboard ### TinyALSA 1. 执行以下命令，以提取源代码树： devtool modify tinyalsa Copy to clipboard 将 TinyALSA 源代码树提取到 `build-qcom-wayland/workspace/sources/tinyalsa`。 2. 执行以下命令，构建源代码树： devtool build tinyalsa Copy to clipboard ## PAL 配置 可以使用 mixer\_paths、resourcemanager 和 usecasekvmanager XML 文件在 PAL 层配置音频用例。 ### mixer\_paths XML 混音器控件是从 ALSA 混音器公开到用户空间的控制变量。支持用户空间访问、设置和获取函数，以及将参数传递给 ALSA 混音器。 例如，以下是用于在 `mixer_path.xml` 中启用单声道扬声器设备的条目。每当触发播放并且选择的设备是扬声器时，将在 audio route helper 类的帮助下触发以下混音器控件。 Copy to clipboard 平台使用的混音器路径名称为 `mixer_paths_.xml`，位于 `/etc/` 目录中。 ### Resourcemanager XML 此 XML 文件包括所有可能的设备、用例和组合。其还包括各种配置、模块参数和全局参数。 下面是在资源管理 XML 文件中扬声器设备的示例。它具有扬声器设备的所有配置，例如后端名称、通道、采样率、位宽等。 PAL_DEVICE_OUT_SPEAKER CODEC_DMA-LPAIF_WSA-RX-0 2 2 48000 16 speaker Copy to clipboard ### Usecasekvmanager XML 此 XML 文件包含每个用例的 GKV 详细信息。PAL 使用此 XML 文件检索每个用例的 KV 配置，然后使用该配置从 ACDB 文件中检索图信息。此文件位于设备上的 `/etc` 路径中。 下面是单流和设备图键向量配置的示例。 **Stream KV** Copy to clipboard **Device KV** Copy to clipboard **DevicePP KV** Copy to clipboard ## MI2S/TDM 接口 MI2s 和 TDM 接口允许设备连接和传输音频数据。 ### MI2S MI2S 是一种串行总线接口，可用于连接多种数字音频设备。这种数据接口非常简单，无需进行任何形式的地址或设备选择。 MI2S仅由一台总线控制器、一台发送器和一台接收器组成。发送器或接收器可以是总线控制器。MI2S 总线的数据线路上承载两条或以上的音频通道。每条数据线路承载双通道数据（即左通道和右通道），用于传输双通道音频数据流。数据在左右通道之间交替，由总线控制器驱动的字选择（WS）信号控制。 MI2S 功能支持： MI2S 支持 | **配置** | Controller 和 Target 模式 | | --- | --- | | **数据格式** | 16 位、24 位、左对齐、32 位 | | **采样率** |

  • Controller 模式下支持 8、16、32、44.1、48、88.2、96、176.4、192、352.8 和 384 kHz


  • Target 模式下的所有标准采样率


| | **位时钟 (Bit clock)** | 最大 24.586 MHz | | **串行数据线** | 串行数据线可配置为 Rx/Tx。每条数据线可承载 2 通道数据（立体声数据）。

### TDM TDM 接口是用于在系统内的设备之间传输多通道音频数据的最常用机制。TDM接口由两个控制时钟：帧同步脉冲(FSYNC)和串行时钟(SCLK)组成，也称为位时钟(BCLK)。此外，还包括两条或多条串行音频数据线（SDATA 或 SD）。 TDM 特性支持： TDM 支持 | **配置** | Controller 和 Target 模式 | | --- | --- | | **数据格式** | 16 位、24 位、左对齐、32 位 | | **采样率** |

  • Controller 模式下支持 8、16、32、44.1、48、88.2、96、176.4、192、352.8 和 384 kHz


  • Target 模式下的所有标准采样率


| | **位时钟 (Bit clock)** | 最大 24.586 MHz | | **串行数据线** |

  • 每个时隙发送的数据可以小于或等于时隙大小


    • Tx – 如果数据大小小于槽大小，则剩余位用零填充。


    • Rx – 如果数据大小小于时隙大小，则忽略数据大小之后的所有接收数据




  • 任何一个传输或接收时隙均可用作活动时隙。
    - 每帧最多可以使用全部 32 个活动时隙


| | **帧/时隙大小** |

  • 每帧 1 到 512 位


  • 每个时隙 1 到 32 位（串行数据输入和输出的宽度可能不同）


  • 每帧 1 到 32 个时隙，取决于编程的比特率和每个时隙的位数
