When importing streaming sound (from vinyl, radio, internet, Spotify etc.) there is a momentary noise like 'BZZZ' every now and then. Sometimes it's a number of times in a minute (e.g. 10-15 times), other times there's no such noise at all. Recording from CD is perfectly fine. Every noise instance is pretty much the same length, about 0.25-0.5 s, I would guess. It doesn't show on the graphics, it's less in strength than the music itself. It doesn't matter if it's in a high or low level part of the music, it appears anywhere.
Going through my old vinyls it's quite annoying to have this quirky noise... Remedy?
