Do I post a stupid question or anybody has tray this ?

I can check, but not until later this evening. To my knowledge, the only thing lost when using higher sample rates is Fat Channel processing.

What DAW are you using, and where are you managing the outputs?

What version of Universal Control are you using?

Thank Matt,
using last studio one and last UC 2.0 they give me 8 in and 14 outs the two main outs the 8 lines outs and the 4 phones out.
If I set the sample frequency between 44.1 and 96Khz in th UC I have 18 in and 24 outs and Spidif is visible in I/O settings of studio one.

I know that studio 192 can handle only 8 channels at the two higher SR but I think there is a bug concerning the Spidif out.

I need this because I can have two more high quality phones out using a Chord Mojo portable dac/headphone amplifier.

I saw the same thing on mine, and confirmed with tech support that you do lose spdif over 96k sample rates.

Thanks a lot for your answer do you think that in a next firmware update presonus will add this?
