Hello all,

My Fireface 400 has been a workhorse for the last 13-14 years. However, a couple days ago, it just sopped passing audio (Input & Output). TotalMix is working and audio level meters are working. The FF 400 powers up and the LED numbers does moves when I move the Totalmix faders. The Host LED is NOT lit

I have power down the unit, updated to the latest firmware, reset Totalmix, try it on my older computer (Trash Can Mac Pro on Maverick....still same result. No audio passing through.

Am I missing something here? Or is my FF 400 finally dead? Yes it has been working just fine for 13-14 years and I should probably get something new. However, I still really like this unit and prefer to get it working if possible. Any help and suggestions will be greatly appreciated.
