I've got a problem with my Line6 UX2.
I've got Logitech Z625 2.1 speakers plugged inside the output port of the audio card (using an adapter). If phantom power is on (no matter if a microphone is plugged in or not) and I restart my computer (or I disconnect and reconnect the usb port of the device), the device produce an high pitched noise on my speakers. The only workaround I found is to disconnect the UX2 usb port, turn off the phantom while disconnected, reconnect the UX2 usb port, turn on the Phantom Power again (and now it works).
Do you know why this thing happens and how can I solve it?
Thank you in advance!
