I2s over HDMI on DX3/Oladra

I am trying to get this working on my newly upgraded DX3/Oladra box with a new Tubulus Argentus , and neither HDMI port are being recognized as outputs on the player dashboard, and is not seen by my DAC.

USB output is working fine.

Is there something I need to do to enable this?

Note that my DAC supports I2S from the HDMI port using PS Audio Standard.

I think you will find that the HDMI ports on a DX3 are for maintenance connections only and do not support I2S. You would need an Antipodes S20 for I2S.

I was wondering about that. There are no Maintenance Only labels on it, however.

@gortnipper
Windyb is correct, there is no I2S output on the DX3, the HDMI is for maintenance monitor use only.
An S20 would be required.

I2s over HDMI on DX3/Oladra How do you like the upgraded DX/3 Olddra. I own a DX3 and am considering the upgrade for my second system ( I own the K50 for my main system ) —

It seems very good. Mostly this week I have been streaming it to my office desk setup, which is a simple Icon2 and old Tannoy monitors. But yesterday I listened a bunch on my main system, and it sounds very nice - very dynamic.
