My question is regarding the I2S_Out_0.

Is the I2S operating as Master or Slave?

Can I interface the I2S on miniStreamer to I2S_OUT_0?

In the RAW mode, the unit is advertising as a 8xIN (7 x MEMS + 1 x PDM input), 2 x OUT (Stereo out on I2S_OUT_0 / Pin J3.1). How to decode the audio recording for the 8 channels?

The I2S out is Master mode. Unfortunately we've never tested connected to miniSTREAMER...
How to "decode" audio of the raw mode? Do you mind to clarify what you mean? These are just PCM out on the 8 x IN inside your PC. No need to any decoding..

@dev team

The User Manual stated "RAW mode: 8ch of audio (7ch coming from the MEMS microphone + 1 ch from spare PDM input) are available as raw audio (non processed)..... Note that in RAW mode, the UMA-8 will output the RAW signal from the MEMS without any digital gain ..........."

I would like to capture the raw audio of each microphones. How to capture the raw audio date? Can I use Audacity?
