Hi there
Back in the driving seat in Bristol, UK, for a few hours.
I have been able to work an unpowered vocal mic direct into Babyface and this connects ok with the Daw. So the input and output in the Babyface are working fine.
I have juggled the optical connection, and no difference, no connection.
On Focusrite OmniPre, the clock is set to 44.1, and in my Daw, the project setting is also 44.1 in my RME Fireface App the sample rate is set for 44.1 also. So they all line up.
As Pioki has indicated, as the Babyface iinput and outputs are working it does seem to be an issue with optical connection.
I attach screenshots of my RME Fireface USB app settings, also my Mac audio midi set up app input and output.
any further ideas would be appreciated.
Barry
