I am new to the software
it was working fine I could record and play back thru my headphones connected to Apollo twin
went to play something back a few days later and it was just playing out of my screen speakers…
I looked through and it says in yellow writing “audio output not connected” in the tool bar right above project window.
I went into studio found where it says audio output tried to connect to Apollo but when I click “connect to Apollo twin usb” it doesn’t do anything
PLEASE HELP!!
