How to config audmux between bluetooth and codec

Hi,

How to config audmux between bluetooth sco and codec wm8962 according different situation.

In our design,

bluetooth PCM connect to AUD6.

WM8962 connect to AUD3

CPU already config AUD2 as ssi2.

How to config AUD6 to AUD2 that using the ssi ?imx_audmux_v2_configure_port?? (The bluetooth sco using the PCM)Is it still SSI ?

Can it dynamic config the audmux when runtime ?Do it need some steps?

Hello Hung,

According to your application, I drew a diagram for you, see following, please !

(1) Don't need to use second SSI

(2) you should do routing between AUD3 & AUD6

See reference manual, please !

Hope the suggestion can help you !

Regards,

Weidong

Hi, Weidong

Thank your help.

According your description, I should set the AUDMUX as internel network mode ?

The other problem is SSI config.

In my design ,

BT is slave mode; Codec is master mode ;Which SSI mode I use?

I search related topic on community , and it maybe set SSI network when use the PCM(BT) ????
