Axe as soundcard dosen't work

[Iloveguitar]

I normally play my mp3 backing tracks through my axe, and jam over it.
Now it doesn't Work "firmware 18".

I loaded firmware 17 Again and it Works.

could this be a bug, or arm I doing something wrong?

Adjust USB Level in I/O.
This parameter was added in fw 18. It's described in the release notes.
