5340 Audio DK FW issue

[Randall Hung]

Hi Nordic

Our customer is going to develop LE Audio porduct and have some question of firmware as below:

(1) Need to use I2S only CODEC (DAC)
(2) Currently using the sample code of the nRF5340 Audio application
(3) This sample code uses CS47L63 as I2C+I2S by default, so it cannot be used directly.
(4) Is there an I2S driver that can be configured with LE Audio?
(5) If not, can we directly shield the I2C source code of CS47L63 and use it?

thanks.

Hello, 

What SDK version is your customer using in their development? Are they using a custom board or our nrf5340 audio development kit?

I will need more information to discuss with our audio experts. 

Kind regards,
Øyvind

Hi Øyvind

The customer use custom board that 5340+codec(only ADC) and SDK 2.8.
