TMDS442 is a 4 to 2 switch so both outputs work at the same time in default operation. TMDS442 is a switch and should not impact the audio data flowing through the device.

TMD442 have any EVM can apply for we test, I browse TI web cant't see any reference designs.
else HDMI switch part also no EVM can test.

does TI has recommend which one audio CODECs use after HDMI switch.

A correction to my previous post: TMDS442 does not drive both outputs at the same time.

Some customers have used PCM9211 however I suggest to take a look at our portfolio to find a audio codec to suit your needs (link to TI Audio Codecs).

The schematic posted seems to be for a RF application and I am unsure to the similarity you are referring to, am I missing something ? Could you provide a simple block diagram of your application.

Are you asking for EVM/reference design files? I am notifying the group over our audio codecs, who should be able to help you further.
