Every now and then I get this cutting out of sound that lasts about 10-20 seconds and goes away. Usually I can never catch it because it goes away by the time I grab something to record it. I finally caught it, just grabbing my phone for a quick video. In this case I had a backing track playing when the sound started cutting out (so it affects USB sound and guitar sound). At first I thought it may be a power supply issue but I tried the supplied adapter and still get the sound cutting out. Anyone have this issue? Video link below.
