Modem audio settings - jack1 - 01-31-2023
I was looking at the AT+QDAI command, and I have 2 questions:
Why mode is slave ? from the docs it says "when slave mode is selected, master and synchronization clock should be provided", so i guess it is provided on the pp... what is it anyway ?
Clock is 256k... why ? I'd pick 2048k
Thanks.

These are settings for the I2S interface providing the audio connection between the modem and the A64. See the schematic to see the connection details. Both ends need to be configured with matching settings for it to work. Modem is slave because A64 is master.

Ok thanks!
Strange because I set 2048k and it works... maybe its wasted clock cycles ?
