new to the forum, first post here and abecause of the problems with my 3 week old UltraLite Mk3. First of all it does that squealing every noe and again where audio drops out but I realise that everyone has those after reading this forum

Another issue is, I want to record from the S/PDIF channel. I have my DJM700 mixer running a digital out into the Motu digital in with a coaxial cable and there is not signal! Thing is , on my Motu front panel I get the reading of channle bumping up and down to music but on my computer interface CueMix I have nothing! And also on the Motu front panel the input meter jump up and down n a weird way, sometimes only left is present, sometimes only right, totally uneven.
Am I doing something wrong? Has anyone had this problem?
Thanks guys.
P.S. Very dissapointed with such an expensive interface and looking to return it if I cannot fix this soon as this is absolutely unnaceptable to work with.
