Hi all

I have some question about Asynchronous Sample Rate Converter (ASRC),

Q1:

If use ASRC convert I2S clock, LRCLK will follow BCLK frequency convert or not ?

Q2:

In the document  i.MX_6_Linux_Reference_Manual Chapter 31 (ASRC) explanation ASRC have two use case,

case 1: Memory > ASRC > Memory

case 2: Memory > ASRC > peripheral

the use case can be convert to peripheral > ASRC > peripheral or not ? if yes how to change setting.

Q3:

If connection the phone with Bluetooth, can be transmission the voice data at the same time ?

PS: Bluetooth use 8K Hz sample rate and audio codec use 48K Hz sample rate, so the ASRC must convert 8K Hz to 48K Hz at the input voice data and convert 48K Hz to 8K Hz at the output voice data.

Thanks.
