''TBDThe Audio interface available on AXEL Lite is based on i.MX6 SoC which provides the following subsystems characteristics: sostituire le sezioni con le informazioni sull'uso della periferica''''Nell'esempio di seguito c'è la descrizione dell'interfaccia HDMI''* Audio codecs are provided by SW, which runs on ARM core, supporting (but not limited to) MP3, WMA, AAC, HE-AAC and Pro10* 3x SSIs* ESAI (Enhanced Serial Audio Interface)* SPDIF Tx/Rx* Audmux* Audio sample rate conversion accelerator (ASRC)
=== Description ===
The Audio interface available on AXEL Lite is based on xxxxx ''TBDi.MX6 processor provides SSI Synchronous Serial Interface port that allow to communicate with audio codecs that implement the inter-IC sound bus standard (I2S).  The SSI includes the following features:SOC name'' SoC.
* Independent (asynchronous) or shared (synchronous) transmit and receive sections with separate or shared internal/external clocks and frame syncs, operating in Master or Slave mode* Normal mode operation using frame sync* 2 sets of Transmit and Receive FIFOs. Each of the four FIFOs is 15x32 bits. The Audio port supports two sets of Tx/Rx FIFOs can be used in Network mode to provide 2 independent channels for transmission and reception (this mode is named as two-channel mode in the following standards and features:descriptions)* Programmable data interface modes such as I2S, LSB, MSB aligned* Programmable word length (8, 10, 12, 16, 18, 20, 22 or 24 bits)* Programmable I2S modes (Master, Slave or Normal). Maximum audio sampling rate is 196kHz. (Note that maximum sampling rate depends on IPG frequency). Minimum audio sampling rate is 8kHz. Network clock (as an oversampling clock to external device) available as output from SRCK in I2S Master mode* AC97 support. Max frame rate is 48kHz. Min frame rate is 8kHz
* High-Definition Multimedia The processor also provides standard Sony/Philips Digital Interface Specification, Version 1.4a * Support for up (SPDIF) stereo transceiver that allows the processor to 1080p at 60Hz HDTV display resolutions receive and up to QXGA graphic display resolutionstransmit digital audio. * Support for 4k x 2k and 3D video formats * Support for up to 16-bit Deep Color modes
