Topic: [SOLVED] FF UC, ch. 3+4 fine in Totalmix but without signal in DAW
Problem:
all 8 analog channels are showing incoming signals in Totalmix (1.65), all channels are present in Audio/MIDI setup and can be selected in various audio applications, including SoundStudio and Logic Pro X.
For some reason unknown to me the audio applications do not receive any input from channels 3 and 4, while 1+2 and channels 5 and above are working fine and can be recorded. All channels are verified to work in Totalmix. But somehow the signal flow ends there for channels 3 and 4.
I reinstalled the driver, flashed the firmware, deleted all relevant Preference files and restarted the coreaudiod deaemon (and of course the Mac). To no avail. And yes, the correct Audio Interface is indeed selected within Logic (and other apps I tested with).
That might be an issue with Core Audio or maybe my Totalmix settings (that are quite ordinary). I'm out of ideas. Any help, pointers, ideas are greatly appreciated.
