I've troubleshooted this issue extensively and I now know for sure that it's a ground loop issue.When I remove my laptops charger, the sound goes away. While the charger was plugged I tried removing all other USB devices, disabling my Wifi adapter/bluetooth radio/webcam - basically anything I could disable&#160; and the problem still persisted.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;">&#160;</p><p>So after researching, I thought I'd tried a USB ground loop isolator as a last resort. I bought a Firestone Audio Green Key Isolator and it was just over $80! I've plugged the GX's usb cable into the Isolator and then connected the isolator to my laptop. Now, it's cleaned up the audio a little, and I mean a LITTLE, but the loud hum noise still continues. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;">&#160;</p><p>I'm going crazy, I've already spent 80 dollars and I can't stand it anymore. Can anyone give me some advice please?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;">&#160;</p><p style="min-height: 8pt; height: 8pt; padding: 0px;">&#160;</p><p>I've attached pictures.</p></div><!-- [DocumentBodyEnd:5a165e71-ba37-4c60-b65a-01452a0646d6] --> Thu, 31 Jan 2013 14:52:21 GMT support@line6.com http://line6.com/support/message/409225?tstart=0#409225 2013-01-31T14:52:21Z 3 months, 2 weeks ago 0
