Finding this thread, I want to comment that I get bad buzzing when recording audio (ground loop issue?) using my Logitech H530 USB headset, and someone told me in some other forum that usb headsets have their own "audio card " on the headset.
I have ordered an usb isolator thingy, which I can plug in between my computer and my headset. I am wondering, if the buzzing I hear, are indicative of deficiencies in the headset, or being a general issue with the whole computer setup. If I knew I could have my buzzing issue go away by getting a more expensive headset, I would be happy, but so far, I have no clue what might remedy my presumed ground loop buzz when I do recording with my usb headset. I want to start recording and maybe stream gameplay so solving this "buzzing issue" is a big deal for me.
Update: I just found a way to remove the buzzing by having a wire around my wrist, connected to my metal computer chassis. Unsure if this represents real health risk. :| I guess it would be the same as if I simply touched my computer case. Hmm. I think I have an anti static bracelet somewhere, I should try wearing that.
Update2: Apparently, wearing the anti static bracelet I bought years ago, which I never used, made the buzzing go away. I have the bracelet clip snapped to the usb plug of my headset, a nice fit.
