HD3SS214: HD3SS214 AUX

Part Number: HD3SS214

Hello,

I am using HD3SS214I as a 1 : 2 DEMUX to steer the display port from graphics card to either a). USB C circuit or b). to an HDMI level translator and connector. Right now i have set AUXSEL as 0 and DxSEL as 1 and using the HDMI connector. When the board boots I can see the BIOS in the HDMI connector. Or only if I boot Ubuntu in special mode - "Try Ubuntu without installing (safe graphics)"  but if I let it boot from SSD normally, I don't see anything. 

This is my previous post

Could this be related to the AUXp/AUXn? They are AC coupled to the HD3SS214I. AUXBp/AUXBn are then connected to HDMI level translator PTN3360DBS and they are pulled up at its input. 

Thanks,
