New UR-824 Adat breaking up help

Hi,

Just got the UR-824 to replace my M-Audio Profire 2626 and M-Audio Ultra R8 because I need to have
more than 8 lines ins. So I hook up the UR-824 and my external ADAT and it’s crackley and drops in and out.

Just got the unit today, downloaded latest drivers… Running Vista 32 bit…

Don’t know what to do. HELP!

Ok that went away on it’s own…
