Lexicon Alpha Input/Output issue??

Lexicon Alpha worked fine last week... Now I can't seem to get it to register sound in GB.... I'm using a guitar plugged into the interface and headphones to monitor....

I am able to hear the guitar fine through the device itself.

In GB I have the Input and Output as the Lexicon.

I wanna say I've tried everything to try, changed input/output selections, USB cables, UBS ports, guitar cables, guitars etc...

All was working well with no issues until a day or so ago. I was able to monitor and record through GB, now it's not even showing it's getting signal in GB... I really can't help but feel there's a system preference I need to be looking at but I've changed and tried all the audio inputs/outputs.

ONLY THING that has produced anything was having the input as Lexicon and having the output as my Bose system. Didn't produce any sound that was usable, mostly garble but it was showing the input at least.
