Please do not jump to conclusions! I wrote earlier that the problem was solved, but the cuts can come back in a week or a month, after which you connect any other device to your PC. Driver 1.9.8 for WIN not delivered me from cuts, although better than the previous . Programs can now control the switching frequency of sampling but unfortunately could not manage to change the buffer size, for example a popular guitar plugin as BIAS FX. There have written that cuts the problem concerns the ASRock motherboards, but Asus me. I wrote above that experienced with my PC 7 pcs different UR12, and only 2 of them - each one a certain USB port does not suffer from the cuts. I want this interface to return the seller. To replace the PC will cost 10 times more expensive than buying another interface, and there is no guarantee that the interface with other PC will not suffer from cuts.
