Digital multiplexer for several audio source

Hi,

I wish to select only one of three digital audio sources as shown in the diagram below.

Could you suggest me any suitable  3:1 digital de-multiplexer for such application?

Thanks

    Eng Lih Khaw,

    Please correct me if I'm wrong. I believe I2S signals require 4 lanes a bit clock, word clock, serial data, and sometimes a master clock.

    In your diagram I see I2S coming out on the right but is there I2S coming into DMUX on the left hand side? If this is the case you will need to find a switch that can 1:3 mux 4 channels. I don't believe we have a 4 channel 1:3 mux and may have to use 2 ICs but I will begin searching.

    Please confirm if this is the type of switch you are looking for.

    Thank you,
    Adam
