Hello, my Line 6 UX2 has suddenly stopped working. I had had intermittent problems with it but it worked fine for a week or so, and suddenly stopped receiving any input from any of my guitars, all of which are working perfectly with my amplifier. If I set up my UX2 as a default playback device in the Windows mixer and play audio, the needle moves but all I hear through the UX2s headphone jack is a high pitched whine. I have tried uninstalling and reinstalling Pod Farm 2, the latest drivers, and toggling settings in the Windows mixer. I have also tried the device on multiple computers, my two desktops and my laptop, all running Windows 10. Line 6 license manager authorises the UX2 and my computers fine. I have tried setting different inputs in the Line 6 control panel applet but still, it is not working. Is there anything I can do?
