Problem with drivers (no "send 1-2" and "send 3-4" read) in dual tone

[gooodmen]

Hi!

The problem is that my computer doesn't read "send 1-2" and "send 3-4" during recording dual tone (mic & instrument) on gearbox. I use line 6 ux2 and gear box, I've tried installing diffrend drivers but so far without resoults (In addition I can say that separetly mic  and instrument work, but when i try  record instr&mic my recording software record for example only instrument or vocal on one path) . Please help me I am being tried since for 3 days make it work ;/
