Topic: UFX output completely distorted
Suddenly my Fireface UFX (USB, SW Version 1.63) is producing complete, over-the-top distortion, when I play audio from my iMac (Mojave OS). It is always the same level, utterly full-on distortion (almost white noise) regardless of the signal volume, or of the volume setting on Main Out or Headphones (as long as they have any volume setting above Off).
Also there is a continuous, slightly fluctuating input signal showing in TotalControl on channels 1-12 (also ADAT 1/2), level about halfway up the meters - yet no sound is heard until I play audio.
I've re-installed Fireface USB Driver v3.20 but it hasn't helped.
Occasionally while trying to figure out the problem, it freezes my Mac - can't imagine why.
MIDI appears to be working fine.
Has anyone else had this problem - and if so, can you recommend anything I can try - or is this a hardware problem requiring repair?
Many thanks for any help!
