Last night my Fireface UC was good and I used it for 11 years.  Now, it will not send signal to the computer.  It just pulses static and all of the lights flash after turning it on.

Can anyone help?!?  I have the power supply going through a conditioner.  This has not happened before and I am very alarmed.

It's just sending a static pop and click signal and all of the lights are flashing in time with the pulse.
