audio - I2S and PCM format - Stack Overflow
https://stackoverflow.com/questions/32367619/i2s-and-pcm-format
PCM is a digital representation of an audio signal. It can be stored in memory or written on paper or whatever. An example of a 16-bit PCM audio sample might be something like 0x0152. I2S is a electrical serial interface used to transmit PCM data from one device to another.
PCM/I2S Clock setting in CYW20706 - Infineon Developer ...

If the CYW20706 is configured as a source, then audio samples are received from a hardware codec over I2S. If configured as a sink, then the audio samples are transmitted from CYW20706 to the hardware codec. In A2DP applications, the audio data is routed over I2S by default and or when the route is configured as AUDIO_ROUTE_I2S. CYW20706 can be …

So there won’t be any register telling the SAI to behave like a “PCM” interface or “DSP/Codec”, or “I2S” interface, but I2S, PCM and DSP/Codec interfaces are different configurations of the signals involved (mainly SCK and SYNC) setting individual registers.

This codec allows digital (PCM raw data transmitted with I. 2. S protocol) to analog conversion. The audio parameterization and the codec configuration are performed through an I. 2. C interface. The codec has a wide set of configuration registers mainly used to: • Program the audio output (speaker or headphone) and input (analog input or digital I. 2. S data, etc.).

requires a codec such as the TLV320AIC3204 in order to interface the system processor to the MEMS microphone. The AIC3204 has an I2S interface that provides the down-sampled audio stream utilizing a clock source from the codec. Alternatively, digital microphones with an I2S output can be used, but they

Hi, I have a problem witch I2S/PCM on my OrangePi, I want to use sound codec device without any I2C or SPI controls, only I2S/PCM to play and record audio witch ALSA. Based on this question and this patch, I tried to use snd-soc-dummy witch simple-audio-card and I was succeed to play audio, but audio capturing does not works. I was checking if there is any data …
