''TBDThe Audio interface available on ETRA SoM is based on STM32MP1 SoC which provides the following audio subsystems: sostituire le sezioni con le informazioni sull'uso della periferica''''Nell'esempio di seguito c'è la descrizione dell'interfaccia HDMI''* Synchronous Audio Interface (SAI)** 4x I2S/SAI (16+ channels, each up to 32-bits @192 kHz)** Two independent audio subblocks which can be transmitters or receivers with their respective 8-word integrated FIFOs* Sony/Philips Digital Interface (SPDIF)** S/PDIF Tx/Rx

The Audio I2S (Inter IC Sound) module provides a synchronous audio interface available on ETRA is based on xxxxx (SAI) that supports full- duplex serial interfaces with frame synchronization such as I2S, LSB or MSB-justified, AC''TBD:SOC name'' SoC97, TDM, and PCM/DSP interfaces.

The Audio port It supports the following standards and features:* Two independent audio subblocks* High-Definition Multimedia Interface Specification, Version 1.4a Synchronous or asynchronous mode between the audio subblocks* Support for up to 1080p at 60Hz HDTV display resolutions and up to QXGA graphic display resolutions. Possible synchronization between multiple SAIs* Support Master or slave configuration independent for 4k x 2k and 3D video formats both audio subblocks* Support for up 2-channel DMA interfaceThe Sony/Philips Digital Interface (SPDIF) audio block is a stereo transceiver that allows the processor to 16-bit Deep Color modesreceive and transmit digital audio.
