For quite a while now I’ve been getting high-pitched glitching from my UR22, or at least I’m pretty sure it’s coming from the unit. When I play sound files off my laptop through it there’s frequent crackling, and when I record this appears as a brief high-pitched electronic sound exactly once every minute, and it appears visibly on the waveform. Occasionally it’ll happen outside of the one-minute time-frame, and sometimes in more extended bursts, but usually it’s regular. This is driving me crazy, as I can’t record for more than one minute without the take being ruined.
I’ve tried replacing the USB cable, which didn’t change anything, and using all 3 of the USB ports on my laptop, which didn’t help. I’ve tried shutting down other processes on the computer too, but this doesn’t seem to make a difference. I have to admit I’m not at all technically adept, so there may be something obvious I’m overlooking. The computer is an HP laptop with Intel Core 1.70/2.40GHz processor, 8G of RAM and 64-bit operating system. I was thinking maybe the RAM is not enough, but this problem has only started in the past few months, and there wasn’t a problem at first.
So I’m not 100% sure, but I think the problem is with the UR22 interface. The problem is the same regardless of input.
This is what the glitch sounds like, just against an ambient drone:
