The snag with words is we all get the wrong ideas. Hiss is the safest, I thing we all get that one. Static is a problem one. Silence then sharp clicks or pops, fizzing noises etc. Some people here have also used this one to explain the digital burbling noises they get when they move the mouse, or save a file? Noise is sort of the generic term for all of this annoying stuff.
this is why we have to hear it, because the solution could be grounding/earthing, your computer, what you have it connected to. That kind of thing, and the6 all have a sort of fingerprint. My friend has the computer type noise, and the cause we found easily. His computer hates his interface connected to his speakers. Swapping computer, speakers or interface cures it, but he’s a stubborn devil and refuses to change anything, demanding satisfaction from three manufacturers! I think I have worked his one out. The interface draws power from the usb cabl. The computer cannot quite supply enough, and the usb voltage drops a teeny bit, but crud from the computer then gets into the usb connection, and the loudspeakers make it audible. It’s not on the interface headphone output, so for him, it’s misery, and the solution is to swap something but he refuses citing his consumer rights etc etc. a filter on the audio cable to the speakers helped a tin6 bit, but my home made one is ugly, so he wont use it.
I suspect you are not doing anything wrong, but there are just so many causes even when we do hear it. Sound loud might work, or if you can’t post it, send it to me and I’ll post it for you if the direct message system allows it?
