We are testing Audio performance by using the evaluation board but we got no audio output.

Please advise how to fix it.

The connection between devices is as follow;

1) DisplayLink DL-3500 is connected to HDMI input.

2) PC SPDIF output is connected to SPDIF input on the board.

We checked if  audio output was heard by only using SPDIF with disabling HDMI audio by using PC setting.

But we heard nothing.

Question; Audio input passes through CS8416 on the board but is any setting for CS8416 required or  just Power-on?

Request; We are trying by changing MAIN MAP(0xBA) mainly by could you provide MAIN MAP value set or the script?
