OSX 14.7.8 has stopped detecting Quad Cortex as sounds device

Hi all,

I don’t know why since today my Macbook pro has stopped detecting Quad Cortex. I tried to reboot everything: Mac book as well as Quad Cortex nevertheless to change cable as well as usb port. Nothing, it’s not being detected again anymore.

However it work : I can interact with the device, play my guitar and getting proper output from the speakers.

Any idea what’s wrong ?

thanks
