# Audio overview

Learn the audio software components and how audio flows from applications, through user space and kernel space, to the audio hardware.

## Audio subsystem

The audio subsystem is powered by low power AI (LPAI) and uses a dedicated hardware-based AI accelerator for machine learning-based work.

The following figure shows how audio data flows between the application processor, the LPAI module, and the codec that connects to the speaker and microphone.

Application processor connected through internal WSA, Tx, and VA macros to external speakers and  microphones.

### Audio system components

The Snapdragon X2 Linux audio system includes the following components:

- The application processor is a CPU that handles audio processing tasks including:

    - Managing audio record and playback.
    - Decoding audio formats.
    - Using LPAI for postprocessing tasks.
- LPAI: Subsystem that runs audio playback, record, and voice-activation (VA) algorithms. It integrates a dedicated Qualcomm® Hexagon™ Processor (QDSP6) and a low-power island (LPI).
- Speaker amplifier and microphone - Playback and record devices that connect over SoundWire, PDM, and MI2S/TDM.

### Audio features

The Snapdragon X2 Linux audio system supports the following features:

- Audio input and output interfaces:

    - SoundWire interfaces (two Tx and two Rx data for codec)
    - Dedicated SoundWire interface for WSA884x smart speaker amplifier
    - Six MI2S (2x data) interfaces
    - One MI2S (4x data) interface
    - Display port (DP) v1.4 (8 channel) MST
- Speaker amplifier: 2 Channels or 4 channels WSA884x.
- Support for audio features, including:

    - Playback
    - Recording

High-level audio software architecture comparing the ASoC and AudioReach paths from applications through user and kernel space to hardware.

The audio software architecture includes the following major components.

Software architecture components

| Component | Description |
| --- | --- |
| Application 1 | A generic multimedia app that produces or consumes audio and sends it through higher-level frameworks (like GStreamer or PipeWire) instead of directly interacting with hardware. |
| Application 2 | Another app sharing the same audio stack, demonstrating that multiple applications can simultaneously use and route audio streams. |
| GStreamer | A multimedia framework that processes audio/video (for example,, decoding and encoding) before passing audio streams to the system audio layer. |
| PipeWire | A user-space audio server that manages audio routing, mixing, and connections between applications and hardware devices. |
| ALSA and ASoC FWK | This layer bridges user space and hardware drivers, with ALSA handling sound subsystem functions and ASoC managing embedded audio hardware interactions. |
| Q6 APM driver | A Qualcomm-specific driver that communicates with the DSP’s audio processing manager to control audio routing and processing. |
| PCM driver | Handles the transfer of raw digital audio (PCM data) between memory and the audio subsystem for playback or recording. |
| DAI driver | Manages the digital audio interface (for example, I2S or TDM), configuring how audio data is transferred between processor and codec. |
| Codec driver | Controls the audio codec hardware, configuring it to convert digital audio signals to analog output and vice versa. |
| Platform Abstraction Layer (PAL) | Provides higher-level audio-specific APIs to access the audio hardware and drivers to enable audio features. |
| Audio graph manager (AGM) | Provides interfaces to allow TinyALSA-based mixer controls and PCM/compressed plug-ins to interact and enable audio features. |
| AudioReach graph service (ARGS) | Consists of the graph service layer (GSL), generic packet router (GPR), and ACDB management layer (AML) modules. Handles initialization and creation of graphs, and creation of packets for sending a series of commands to the AudioReach Engine (ARE). |
| Audio calibration database (ACDB) | Includes information about various audio use cases such as graphs and module calibration data. The apps processor parses ACDB files to get the graph information used by ARE to enable the use case. |
| AudioReach Engine (ARE) | Modular framework that runs on the LPAI DSP. It helps set up, configure, and run signal processing modules for audio features. |
| Qualcomm Audio Calibration Tool (QACT™ Platform) | PC-based software that provides a GUI to visualize, configure, and store audio graphs in the ACDB for audio use cases. |
