So have had a fireface 400 for many years in one particular workstation and it is playing up. (win10 setup)

On power up there is no sound for several minutes and then a short squeal and static sound through outputs and audio then passes.

Also for the first time Totalmix is not recalling it's saved snapshot and failing to load the presets (resets to mixname : Mix 1, 2, 3 etc)

Found this thread on gearslutz which sounds like same issue for sound problem due to capacitors although I took the fireface apart and there was no obvious signs of cap bulging etc (I know bad caps wont always show visible signs)

Anyone have suggestions or knowledge of this?

Many Thanks
